The 23rd looks like the best time - no objections to it so far, whereas the 30th isn't good for some.
The best location would be something central to the whole area, I think (though I could be wrong). A big thank you to Project Big 1 for the offer of hospitality, but perhaps its too far south? Ditto for Front Royal. Though it would be cool to have in my back yard, and the Skyline Drive is beautiful (its 4 miles from the house as the crow flies - we go every weekend), it might be too far for the Baltimore/DC/MD people. Again, I could be on crack with this - anybody have any thoughts?
How about this - all for the 23rd, say aye. We work on location next. Tell us where you are NOT willing to drive. For me, I'll go anywhere.
