Thanks for the summaries, I knew ALB and BGM were going to sink my chances ... by the way, check in the summary, BGR max forecast not the closest, think it was maybe second closest? Otherwise all looks right at first glance. We all had our ups and downs in that one, but I hit max turbulence. :)

In re the BGR max forecast; Thx for the eagle eye. It's an eyeball analysis and sometimes it's less than 20/20.
