Especially local events. Check to see whats going on around your area.
This isnt uncommon. Some of the bigger shows, such as breed specific shows, you will find that there are some "youngsters" that are brought, even though they are not completing. When ever I have one I am preparing for show, I bring him/her along with the ones that are showing. It's an exposure issue. If I have one that is up and coming for a Weanling Halter class, the last thing I need is baby to get completely "ill mannered" in the ring. So by bringing him/her to prior shows to their own, they become familiar with new areas and strange environments, and are much more comfortable when it comes time for me to show them.
Events such as Gymkhana's are great. Those are generally local, lots of socialization goes on there, and tons of fun events. Ask a friend who may be going if you can piggyback yours along for exposure. It's not uncommon. If there are horse clubs as well in your area, get in touch and explain that you want to expose yours to a variety of events. Then even if there are any closed events where equine not enrolled can not go, then they can line you up for practice events they are already holding at group sanctioned arena's. A little here and a little there, you will find out a wealth of information yourself, as well as the baby!
