Sinnemahoning State Park is really awesome, but no FHU's.
Places close to where the Elk are, are limited, especially with FHU's.
"so travel distance is a bit of a concern" That is what it is, but your not talking thousands or even hundreds of miles. Just make sure you fill up with fuel once you leave / north of I-80 no matter where you go, gas stations can be few and far between, especially on a Sunday where they roll everything up early, and you may as well shut the electronics and cell phones off.
