Very nice UrbanBoy, I like how you think (usually)

. In addition to the energy complex on the Holdings block how about another couple of 25-35 story towers a couple of blocks off Main, maybe widen the skyline from E-W. Maybe on the block south of ESA, like a W hotel or something.
400 S was recently rezoned to allow larger heights, I can't remember how high how, but I'm pretty sure it's at least 15 -20.
