Until you actually know how many games I have been to, STFU and stop being so irate and irrational about things.
It's very clear from your post you feel you have been "slighted". Well guess what..the parking lot is a PUBLIC PLACE and must partake in actions that are best for teh PUBLIC. Not for a few people who want to get their party on. Just because tickets and parking are $X does not mean you can do whatever you want. If you do not like it, do not attend, it's that simple and that's what they will tell you. It's much like this site, if you don't like the way it is leave. There is no "free speech" here since it is privately run, just like Dolphin Stadium is privately run.
It's hard for you to understand this because your little parties are getting the kabash, but it's clear that the Dolphin organization, stadium workers, and the community don't like the things you mentioned. It makes their lives troublesome and it shouldn't effect your fun to remove it, but in turn will make their job easier. And think, back in the 70's people just went to games and cooked/drank in the parking lot

.. how did they manage???
