Bill-
It's rather simple, really--drive a block or two, get out, walk back to the second car, drive a block or two past the first one, walk back, drive a block or two past the second one, walk back, etc, etc. I plan on leaving for the meet about 4 days before-hand, to ensure I make it on time!!
Seriously, though, I'll drive one, my Girlfriend another, and friends of ours ( John & Michelle) will drive #3. They went last year, and had a great time. So much so, in fact, that Michelle is still searcing for the "perfect" XR2 to become her next baby!!
