I was going to suggest this one, as well as a few more within a couple of exits either way from this one. There are actually quite a few between Harrisburg (approx @ MP 55) through MilePost 105 I believe. I frequently go through that area and there are definetely numerous ones through that area. Time-wise to MP 100 is approx 35-40 min from Hbg. There is also a rest area at MP 80 that you can overnight in if desired.
