Rob,
Yeah - it doesn't take much to get very crowded in either space. My bigger concern is wind - it looks so calm out there right now there is not a leaf moving anywhere.

The wind is perfect at Gasworks when its coming from the South. The trouble is that the terrain is extremely hilly there, so you need to be careful you don't fall down a slope or back into the bay!
I've seen Everett fly there - he's amazing and you are right the scenery/backdrop is beautiful.
