They tried that in Cincinnati last Spring thru early Summer.
I have a suburban horse/chicken farm in the northeast corner of Cincinnati. And we are overwhelmed with raccoons and possums.
I was catching at least one a day with a high of four raccoons in a day in my live traps.
I would cart them all down to the tent city and let ‘em loose. And bring a few packs of peanut butter crackers to hand out.
The fact that the tent city became overwhelmed with raccoons made it onto Bill Cunningham’s radio show!
