Jim raises a good point about the "success" of these trips being related to a sell-out. Obviously we want as much motivation as possible for repeat performances. I know some motorcaders will want to make a contribution. As John Craft pointed out in an earlier thread, one way to do that is to simply make a donation directly to DRHS. But if for any reason the trip you are chasing does not sell out, buying a ticket rather than making a direct contribution might have more impact in encouraging future trips. Or hell, do both, it's a good cause.
