Camper Jeff & Kelli,
Yes the observatory is open year round to public viewing...best to go on a clear, dark evening - very interesting. The park is pretty good, there are plenty of sites away from the road, but there is limited shade/tree cover in the RV spots (about 5 or 6) and only some of the tent sites would level or accessible enough for a TC. Unfortunately, there is really no fishing in or around the park since a few of the beaver dams that had long created some good backwater "lakes" have been wiped out and now the river is really just a 4ft wide creek that is real shallow.
I like the idea of the wobble stoppers, except I think they mount to the inside (truck side) of the jack leg and that would further reduce my clearance to my dually fenders. Right now I have less than 2" between them, so unless I am wrong about how they mount, it might make for a tough loading/unloading process.
Thanks for the good tips on camping!
