Get what you pay for
Pros: Free, many sites with water access for kayaking/fishing, fire rings, parking lot close to sites. Cons: Lots of road noise-- you're sitting in a valley bordered by highway on 3 sides, and the echo is serious. Trash everywhere making some sites unusable. Lots of poison ivy.
So, if it's worth it to you for a free spot go ahead. You'll basically be camping in someone else's backyard, there are several residents.
