I agree with the above.
Also I know in the small local shows around me, unless your horse has very bad conformation, its all about turnout, turnout, turnout. Pay extra close attention to grooming up and looking professional.
I know its a small show, but if you look like your going to or in an A rated show you will do better. Treat every show like its the highest level show... don't assume just becuase its a little show you can slack off or skimp on the important things... ~
Give the horses a really good bath, get those whites so bright you can't even look at 'em. ~
Practice banding or braiding (whatever you plan to do) every day so when the show comes around you can do it fast and perfect. ~
Dress in suitable attire. You don't need top of the line expensive outfits but look for somthing very close (just a bit cheaper) try to look like you know what your doing and how you are expected to look, even if you are unsure... You can always look up big halter horse shows and try to minic the attire the best you can. ~
Make sure everything (like halters) is clean and looking tip top. Never use an old dry-rotted halter or a rusty looking chain.
