I agree with Jerry 100%.
I also agree with R&K, somewhat. Rather than switching the venue every month and making one group or another drive very far, I'd like to see a switch to a more centralized location. An easy way to do this would be to use something like
http://www.frappr.com to map out the majority of the group's locations, and try to find something in the middle.
Though honestly, the drive from the west side to east, or the east to west isn't really that bad for 1 day a month
Just my two pennies.
