Rally: May '07

I'm beginning to orginize a timed rally for vintage motorcycles. The format will be similar to an off road enduro. Takes place in Paso Robles, CA (about 12 way between LA and SF)2nd weekend in May. Should I open up a seperate sidecar class (regardless of vintage)? Bike entry will be limited to 60. If I add sidecars I'll need to expand the program and will need volunteers to man check points. I've discussed this a little with Medina at Irbit Motor and we might get some help from them. Show of hands, please. Thanks, Chris Sidah.
