We have a very nice Gulf front park, Ft De Soto County park here in Florida. No alcohol allowed. The park also has a FB page where you can check in and post pictures. So, some of the young party crowd "checked in " on the park FB page and posted a picture of their beer can pyramid at their campsite. Unfortunately for the party crowd, the FB site was monitored and LE was called to eject offenders and issue citations. You can't fix stupid. No alcohol means no alcohol.
