A 3 wood away from me bud, I'm in Fonda. The Fonda Fair is running through the 7th. Really popular in this area.
As for boat rentals...there are lots of 'em on the lake, the best is Northampton Marina(518-863-8127) near the Northampton Campsite(NYS operated camping)
What are your actual visit dates??

If the Fair is up your alley(I'd be there if I was more mobile) you can park in my yd and walk to it..about a 5min walk and save 10-15 bucks parking.
