El and Bill,
Good Ramp in Hessel and Cedarville but overnight parking not so sure.
The launch at Cedarville has a park lot across the street but used to have signs saying no overnight parking. You could launch at Raber and just leave the truck there for a month as you visit these wonderful spots.
Maybe Hessle Marina will give you a break? Cedarville has a grocery store and a good sandwich restaurant two blocks from nice little public day dock. The restaurant and store are on the highway. Restaurant is named Pam's or Patricia's something like that. Cedarville has a small museum one block from dock and a larger maritime museum 1.5? miles west on the highway. The MM has old wood boats, the first four stroke outboard, some other okay stuff to look at.
Hessel has a marina, and Mertaugh? sp? boatworks. Once a year they have the reunion for wooden runabouts and there are a number of these boats in the islands. The Dollar Island house has fallen into disrepair last time I was there but is still unique. Hessel has a couple of b and b type places with beautiful grounds.
If you go to the E end check out Port Dolomite, likely to see a freighter loading or enroute.
There are some cuts you can go thru in a c-dory in the daytime that most boats can't. The area has perch fishing and lots of old boathouses. Government Island is not privately owned, most islands are, but you wouldn't know it from their quiet appearance.
Regards,
