I few months back I thought West Branch SP would be a good place for a Pond Piggies Memorial Day weekend. I checked today on their website a saw they only had 5 full service sites left. Their electric sites for that weekend are only 25% taken so far. Mike did a good job setting up Cutty's for that weekend last year. I was kind of surprised that they were able to get us all into the same area with full service. I think state parks are hard to book group campouts during the summer and holiday weekend because they fill up so far ahead.
Just a note here. Over the last two Oct./ fall seasons we have camped at both Mohican and West Branch fall / Halloween camp-outs. If you get into Halloween and have kids these is a great time. This year Mohican is having it two weekends (Oct 13 - 14) & (Oct 20 - 21 ) and West Branch is having it (Oct 13 - 14 ). We went to West Branch's last year and they had a Haunted Trail (about a 1/2 mile long) done with about 100 volunteers (great job)

. On Sat. early evening they close down the roads ( no car travel) for the kids to trick-or-treat for about 2 hours. A lot of people go all out to decorate their campsites. For both of these we made reservations about 3 months before hand.
Were still up in the air on our summer travel plans. We usually do a week in June at Laurel Hill SP in SW PA. A week in July at Mohican. And then 2-1/2 weeks somewhere different in August. Last year we did 2 weeks at Cooks Forest / Clear Creek Forest in Northern PA. Diane really liked that trip. At Clear Creek your right on the Clarion river. Its a very quite / low key park.
