For info on LW or Pawtuckaway...try Newenglandbouldering.com.
LW is more crimpy while P'tuckaway is more diverse with crimps, edges, slopers. Both can be sharp, especially LW. At P'tway, be prepared for some "fun" mantles....
Tim Kemple's guide to Pawtuckaway is good, and a there was an article in Rock and Ice about LW a year or so ago (it was the one with the poor b*st*rd in Kansas climbing the telephone pole with ice tools on the cover...)
Camping is limited at both, LW is pretty much a urban park, and there may be campgrounds around P'tway, but camping isn't allowed in the park.
And yes, there is are places to eat around both parks...they're in New England....not some wilderness area.
Late spring and Fall are the best times for both. Both can be climbed at during the winter, LW can be better as it gets less snow. P'tway gets more snow, and is colder, the boulders are often located in evergreen stands, ie, less sun. In the Summer; LW is an urban park....boomboxes, screaming childern, etc, and P'tway is buggy, very buggy. Did I mention bugs?
There is also some short roped climbing in P'tuckaway, but with few exceptions I think the bouldering is much better. Roped climbing is prohibited in LW.
