Blue Heron Pines-East. I really like BHP-West, and most people, inside and outside of the treehouse, I have spoken to say East was better-more compelling architecture.
Obviously, I have no basis for comparison. I recall seeing notices of this closing sometime around the end of 2006 or 2007, but never made it down to Atlantic County to play it. (Now, I live 15 mins away and pass it daily).
Ashbourne was another missed opportunity in '06-'08, when I lived a few miles up the road in Montco. And, I could have played with Bausch and Harris.
I was happy to have the opportunity to play Beechtree about once a year from 2004-2007.
