Need Help Finding or Starting Lead Club in Rochester, NY

I'm trying to locate an existing Lead Club in Rochester, NY -- a
weekly or bi-weekly meeting of a group of sales people to exchange
leads, tips & referrals.  I know there are several professional
networking organizations in the area, but I was looking for something
a little less formal, and without the annual membership dues.

Any ideas on where I can find such a group?  Any advice on starting
one up?

Thanks,  

Chris.
