I guess I've been giving out mixed messages. Let me ask it this way:
What is the smallest size arena I can jump a 3ft course in? I'm not looking for anything elaborate. It's for my own training purposes. I do want to be able to practice what will come up in shows though, maybe just in a smaller scale. Does that make sense?
Maggie- Thanks for the advice on building it so it's not hard to expand later when finances aren't so tight.
