I've never read any reviews on Camp Dearborn but I have been there at least once a year over the last 5 years and never experienced any of the stuff reported by drsteve (not sure if he is saying those things happened or if he is repeating reviewers that say it happened).
We are actually going to Camp Dearborn ourselves in mid September (second time this year). I have never had a problem there. I've also been to Haas Lake and never had a problem there either. I like camp Dearborn because it's reasonably priced, bathrooms are clean, there is a lot of stuff you can do there, good sized sites, just all around nice facilities. I guess my experience has been different that what drsteve experienced (or is repeating from somewhere else).
