If my desk job from hell has taught me anything, it's that it is IMPOSSIBLE to plan or publicize an event (big or small, and MarineEX in your town qualifies as FRIGGIN' HUUUUUUUUUUUUUUGE) enough to avoid a mountain of problems.
Better to cancel an event that's not properly planned (and take the hit in the press) than to allow it to move forward with the resultant consequences.
Case in point:
...and Dayton sees it every few years and these things STILL happen. Now imagine what happens in a city that hasn't seen it before.
I agree. TRUEX is a very well planned event, and is publicized in the local media (TV, Radio, and print) for MONTHS leading up to it. The planning involved includes representatives of the local government, police, fire, FAA, and the USMC. They know we're coming, at least in theory. That's why we're only allowed to fly certain routes, and land in certain LZ's. The buildings we use for urban ops are abandoned, or are volunteered by the owners. Most of them are in the slums (case in point - on a night fam, the Hueys came back with Star Saphire tape of what we think was a drug deal going down. We got to watch them scatter like cockroaches when the skids flew over, my guess is they thought it was a police helicopter), and for the larger portions of the exercise (not the fam portion), the cops & fire deparment are there doing crowd control. We also make it a point to do a lot of public affairs type stuff along the way, landing and shutting down at local schools, etc... Yet - there's still some people that don't get the memo or are pissed off that we're there, and the press (even though they know about it) would always come up with something to write that was negative about what we were doing.
If this level of coordination is not present, then it would be logical why a local government would be hesitant to sponsor our training. We do the same sort of thing in Yuma during WTI and Desert Talon. My guess is that since they see it 2-4 times per year, that they're aren't as surprised when it does happen. Plus, all the LZ's are generally on the outskirts of town and are HIGHLY controlled by the cops. I do find it amazing that the "tribal leaders" are always having "meetings" at one of the local strip clubs (at least that's the scenario, and the LZ is right next door)...
