what to bring:
everything that you would ordinarily bring to a show, plus extras of things like halters and leads, reins, etc.
lots and lots of buckets
a tack box or storage container that can lock (take a look here: http://www.lowes.com/pd_101939-46921-101939_0_?productId=3099503&Ntt=stanley%20job%20chest&Ntk=i_products&pl=1&currentURL=/pl__0__s?newSearch=true$Ntt=stanley%20job%20chest$y=0$x=0 )
saddle stand to store tack during the day (you’ll probably want to lock it up at night just in case) (i just bought this one and i really like it, it has a bridle hook too: http://www.statelinetack.com/item/procraft-folding-saddle-stand/SLT310345/ )
hay bale bag to store hay
hay feeder bag (the nets can be dangerous, and horses like the bags) for feeding in the stall

those are things i’ve been advised for this year so far. if i find out any more, i’ll email you good luck at county and state!

Bring all of your grooming supplies, brushes and hoof picks are super important. Show Sheen or a spray that makes your horse’s coat shiny and glossy. If your horse is white you’ll probably want some spot out just incase he gets brown/green spots from sleeping in poop (which isn’t uncommon) in the stall. Bring a small sewing kit incase an article of clothing breaks. You will definitely want back up boots or boots and half chaps (if you’re showing English) incase something goes wrong with that.
You’ll also want to bring a bill of sale/bill of lease for registering for classes and such unless that has already been done. You will need a hay net and shipping boots for trailer rides, all of your food etc for the horse. I’m sure you could go online and look up lists or what not because I know I’m leaving a lot out.. But my advice would be to look up a list to make sure you have everything youll need. Good luck and have lots of fun!!!

For your grain, take plastic bags and pre bag your portions, so all you have to do is open the bag and dump. Hay storage you can use the 55gal contractor bags – again label your bag, your horse is used to his hay, and it all starts looking the same after a few days.

Does your horse do well drinking away from home – mine did not like the city water, and we had to bring water from home for the first day, and mix in the other water.

If your club does not have a barn duty schedule see about setting one up, that way you all get to enjoy the fair, someone is always at the barn, be sure you have a card with your emergency contact number to put on your stall, with your vets name and number as well.

Get your paperwork in order – does your county require a premise ID on your registration form? ours does now, be sure to get that from the barn owner, if needed

Reevaluate your vaccinations – do you need an influenza booster?

Those are a few of the not so obvious things I can think of at the moment….

When we go to shows, we put the hay bale in a garbage bag. It works just as well and it’s easy clean up. It also works to line the floor underneath the bale if we have to set it on the ground outside the stall, and it’s easy to put loose hay back in it.

Bring a chain or something to secure the water bucket. If it has a handle, it doesn’t need to be left on the ground. Haystrings work well as cheap ties .

Have all of your grooming/wash stuff (brushes, clippers, shampoo, sponge, wash bucket, fly spray, combs, show sheen, etc.). You might want to invest in a hose, or make sure someone from the barn has one. Not all wash facilities come with one, and occasionally they are broken, missing, have holes in them, etc. You might also want to bring a sprayer attachment for the end of the hose. Bring a box fan for your horse and brings ties (again, haystrings work!) to secure it to the stall. I suggest bringing an extension cord and a multiplug strip as well because there are never enough outlets in the barn. Use either plastic zipties or electrical tape to secure any electrical cords to the tops of the stalls so they don’t hang loose and get chewed on by a horse. Bring a sign for the stall door that has your name, barn name, and contact info in case of an emergency. Bring something to secure the stall with if there is any doubt about the suitability of the latch (our 4-H barns have horrible latches and we always put a halter or chain around it as well, just in case). If you get a tack stall, bring a lock. I like having a tack hook/hanger to put bridles, halters, etc. on when I’m rushing around getting ready.
