You can visit the Passport America web site and they have a list of campgrounds with maps

Depends where in eastern PA you're looking, but as already pointed out not much will be open around here until April 1 or after. Otter Lake has been mentioned. Lazy K in Boyertown/Bechtelsville is open year round but the owner has a reputation for his temper (or lack of control of same). There is a KOA in the Jonestown area off of I-78 that is also open year round. Finally, you may want to look in to Pine Hill near Kutztown/Krumsville PA also right off of I-78. I've often seen rigs & other activity going on there even when they are not officially in season.

You'll have better luck south of the Mason-Dixon Line before April 1. Happy hunting!

Thanks jtbr....

Thanks folks!

Greenbelt Park, just north of D.C. and east of College Park, MD, has a good National Park Service campground convenient to the Metro train and bus service. Reservations through recreation.gov are probably a good idea.

boondockerswelcome.com & HarvestHosts.com are 2 separate organizations that allow free overnight camping. Yes I have used both for the best camping experiences of my life.
boondockerswelcome costs $10 if you can return the favor or $20 if not to join for a year.
HarvestHosts is $40

Pickins are slim for eastern PA. For March/April finding open CGs may be a problem.

For Baltimore there is a KOA on I97 SE of BWI airport.
For DC there is a county/municipal CG in Reston, VA.
For Richmond, VA there is a CG on the grounds of the raceway.

That is about my limit of local knowledge.
