This was the first time I organized this event, so there's no "generally" that we can reference. Another group drove a similar route up Mt Greylock a few years ago. We're thinking of a repeat next year, but a bit earlier in the season for better weather. Of course it would be great to have you join us if you can.
There's an excellent annual event in Watkins Glen NY annually, the Green Grand Prix. On the historic twisty turns track. That is closer to Rochester. Driving in that event is an absolute hoot, highly recommended. Here's the link for the April 2014 GGP:
