What side are you moving to? I just moved from just outside St Louis on the Illinois side to Colorado last year!
Look into MOHJO and MHSA should have show list from around the area. Alot of good shows are at the NEC at Lake St Louis, including Irish Fox and Queeny Productions, I belive that is wear the Bridlespur show is too but not forsure. Another show my barn went to was Ridgefield charity Show. All these are on the MO side but easy to get to if you want to, if you are on the IL side I can give you a few more schooling shows if you want!
