Mendenhall Camp Ground

Wondering if you folks can help me - I’m headed camping soon at Mendenhall Camp Ground

I have a few questions

1. Are the bathrooms usually clean?

2. Does the campground get crowded?

3. Do the bears come out frequently looking for camper food?

4. How are the bear / food boxes? Are they pretty reliable /secure?

5. I’ll have kids with me - anything I should know about the experience with kiddos running wild?
