RSS, I've never seen FQHA have shows, there are a couple good associations and quite a few that are just jumping on the bandwagon to take money for papers that don't mean squat.
FQHR has quite a few state affiliates and a large year end show, NFQHA has shows as well but I don't think they are quite as large as FQHR. The FQHR shows I've been too have been pretty decent turnout and some quality working horses, several that do both foundation as well as AQHA working events.
Life is like a camera. Focus on what's important, Capture the good times, Develop from the negatives and if things don't work out, Take another shot.
