BobwhiteQuailLover, the former Toby10? Yep, sure enough. Great looking little horse!
Hopefully you have already started working with him daily on the sights, sounds and noises of a parade, it's time consuming but sooooo worth it. We have a tiny town, too, but last year a young horse spooked and went a little nuts before they got him calmed down. Only the rider and 2 other people in the crowd were hurt, but between the town, the parade managers and the injured the lawsuits are flying! Sad thing, they're saying no horses this year.
Since you are a novice and Toby is too, I'd suggest you stay next to a more experienced rider and calm, older horse he knows, just in case he does spook. Maybe even on a lead, so you can have one hand free to wave at the crowd!
HopeMissouri has some great advice.
Have fun, get lots of pics and post them here, okay?
