Okay I've given it some thought.
A banner while flashy, probably won't get seen by a lot of people and isn't in UM's face for long enough.
A billboard would be up longer and be seen by more people. but if we can't find a prime location by UM, there really isn't a point to putting one up in Tamiami just for the **** of it. Plus who knows how long it will take for the ones that we'd want to become available if they're under contract with a business for X months.
If we want go get something up and voicing displeasure as soon as possible I think we need to find something that meets in the middle.
What about one of those mobile billboard trucks? We could probably get something lined up relatively quickly, and we could get it far closer to UM than simply a billboard.
