CB...DW & I have a river lot within walking distance of Little League. We can literally hear the play by play as we relax by the river! There is a KOA 15-20 minutes south on RT15 (runs right by the stadium) that may be the closest campground. Nittany Mountain I believe. You will find a few other private CG's within that distance...most located on the susquehanna river as you go south. If our 5er isnt at our lot, its usually at one of the state parks within a reasonable driving distance...Little Pine SP is about 35 mins from S. Williamsport and has full hook-ups. Nice and quiet...ample room for your rig. Lots of other SP's and private options within 30-40mins!
As far as LLWS goes...its a blast! The kids will love it! Message me if you make the trip and Ill help you with things in the area!
