To get someones address to meet them in person you have to talk to them first. I honestly wouldnt feel comfortable asking a member for an organizers address unless they had an actual business. The people I was working with are as close as you can be to the autox events. As far as image, there are plenty of CR members that do autox. Over half of the people that would go to the event would be the same that have already gone to events.
With rentals you have to pay a deposit and in some cases pay before the race day. Its not them taking a risk, its us taking a risk by paying a deposit hoping people show up. Trying not to lose a deposit is pretty stressful, especially when it comes from the CR fund...
