if you dont register as a competitor are you allowed to ride a uni, or not due to insurance?
No. See post #15 in this thread.
But you can register as a non-competitor and I am pretty sure that is what he is talking about.
I am pretty sure you can ride if you are registered as a non-competitor, just not in the competitions obviously.
i was planing on doing a non-competitor registration
EDIT: just saw spencers post, i was going to compete, but i can only make a few days because of work
