Re: Raystown Lake...Huntingdon PA
harp96sho, Snyder's Run boat launch is open again - was closed for some resurfacing and paving improvements. There really aren't many places that you have to be careful of while on the Lake - other than it is busier than anything over the weekends. But during the week you can have her pretty much to yourself. The point across from S-1 is a shallow point, but it is marked with a bouy. Off of Mile Marker 5, 8, and up at 26 (I think that is the one) are also shallow - go wide on those points (we literally fished someones lower unit out of the water on 5 a few weeks ago - it had been submerged fro quite a while).
As for camping without taking the boat out of the water, there are a couple of boat-to-shore camp sites (Nancy's Camp is at Mile Marker 14, I believe, and Snyder's Run is at Mile Marker 2) that are primative, but nice, and free. Also, there are several different Camp sites at Seven Points and Raystown Resort (opposite ends of Lake and Seven Points would be closer to you) that you can get spots on the water, or close to it where you can leave your boat in. Some of these are reservable and others are first come, first serve.
Huntingdon is my home, so if you are heading up, give a shout and I can show you the places to eat, sites to see, etc. Just let me know what you like to do and I will point you in that direction.
