I just read on the published protests that Ride mangers can refuse entry
with cause.
Ride managers put on rides; the AERC merely sanctions them. Ride managers
take all of the risk and do all of the work so that the rest of us can enjoy our
sport. The Committee is not inclined to second guess a ride manager's
discretionary decisions. The Committee will generally defer to a ride manager's
judgment when it is exercised reasonably.
