I have been planning to film the drawbridges across the Chicago river for 2 months now. Finally after much worrying and trepidation of what could go wrong, I got to downtown Chicago this morning around 9am. Just a few tourists out. So I did all the basic checks and put her down to get the satellites. OMG, the bridges are going up for a flotilla of boats! This is an orgasmic video I'm going to have here. No sats yet though. 10 minutes nothing, 4-5 back to 0. This went on for 45 minutes. I moved it all around the bridge. Down the street a bit. Nothing. Bridges all back down, disappointing. It would also lose connection from 1 inch away. Tried a 30 second flight, but too much swaying away. Just missed a lamp post. Finally I decided that this whole thing was not a good idea. Apparently too much interference and the buildings where blocking sats. Even if it did get 6 I feared I'd lose sats while in the air. Kept thinking about that Manhattan video where he flies onto a building then just misses a pedestrian. In the most disappointing moment I just said, "It's over". Packed up and left. My dream crushed. Any thoughts? BTW, then went to a state park on the bottom of Lake Michigan in Indiana and got some great video. So the day wasn't a total loss.
