Looks like I was all wrong previously stating the worse of mud season would be out of the roads by then (anyone may want to reconsider any suggestions from me!). The forecast for this week brought us back into more traditional patterns but heading into the weekend is some good winter-like conditions, another round of challenge on the way for the gravel roads. I'm very glad as I was needing frozen conditions to work in the woods (people depend on this).
VT Digger is running a story today about the 2004 Coventry situation. I lived in Tunbridge, VT in the early 90's when a Dead show in VT occurred in Highgate, with a Phish concert the next day at Sugarbush. We thought we had it all sewn up as 'locals', but spent many hours in the car very close to Sugarbush and missed the entire first set. Early in the 80's I recall sitting far from Hershey, PA on an interstate in a concert traffic jam. You could buy a t-shirt from people walking by, as well as just about anything else from people taking advantage of commerce opportunities with the stopped traffic.
My guess is eclipse watchers will value not abandoning their vehicles more than Dead/Phish heads, and with this event all they would have to do is stop where they are and pay attention.
Correction: Read it on NHPR.org website this morning and then heard it aired on VT Public
