I was looking for a safe place to solo car camp on my way to Colorado. On a Tuesday night it was just myself, an RV and the host RV. LOTS of mosquitoes until the rain started. I had put up my Clam Popup using lag bolts and an impsct drill into the hard ground. I was surprised to see it gone when I got up at 430 am. Once it was light out, I went searching and found it crumpled, but undamaged, near the lake. The rain softened the ground and the winds must have come up.
Anyway, i didn't see trash that others mentioned. If I hadn't had mosquito repellant I would have been miserable, but otherwise it was a nice campground with a pretty view. Very faint train noise, nothing that woke me (than again, i guess i slept through some decent winds).
I didn't use their restrooms due to other reviews (I travel with a potty bucket), so unable to comment on them.
