If its your horse's first show, don't worry about it. It's going to take time (possibly the whole YEAR of showing, or longer) to get him use to a show environment. He going to be calling for his buddies and he's going to be nervous. It'll get better.
As far as the crazy barrel horses present at the show ...... you can't go to a barrel race anywhere without some poorly trained barrel horses. Barrels appeals to a lot of people because they think it is simple to run around 3 barrels, low entry fees (in comparison to other things), and really no tack requirements at all. So you are going to get lots of Joe Schmo's and fire breathing dragons.
Just do you best to ignore them and do the best you can with YOUR horse. That's all that matters. Sounds like you had a successful day overall. Congrats!

It is not enough to know how to ride; one must know how to fall.
