George,

Happy to help. Answers interspersed below:

Where is the parking area, on County Highway 10?
Is it near the Whitney Head Quarters?

The parking area is at the Headquarters, just across the lake from the
Camp on the Point (The fancy 3-story Whitney place on the lake).

I understand that there is some kind of self check-in where you post
on a bulletin board where you are camping?

There used to be a sort of tote board, like at Stillwater, on which
you selected a site and moveda numbered tag from the unoccupied to
oppupied side. This didn't work very well, so now you just sign in on
the log book and paddle in looking for a site (no pre-registration).

Any more info you can give to get me started, or pointers for maps or
books?

I'm going to e-mail you a copy of our campsite rating system for
Little Tupper; this has every site on the lake rated and ranked in 7
categories: maximun tent capacity, landing ease, views and water
proximity, buggieness, swimming potential, site wanderability and
sun/shade mix, along with a cumulative ranking for each sites total
score and notes and comments on each site..

E-mail me your postal address and I'll mail you a map of Little Tupper
with the campsites denoted and numbered.

Let me know if you have any questions or need anything else.

Mike

Thanks in advance,

George
