1) Can anyone recommend a good Cape Cod campground for home base for a short bike tour? I would be departing from Brewster and heading east. I've camped at Nickerson State Park before and didn't enjoy it---it was huge and crowded.

Criteria: treed sites; privacy; not too crowded; near good biking and a beach.

2) Any good stealth camping on Cape Cod? I'm actually not a big fan of campgrounds.
