Good news.
I just used the Strasburg supercharger for the first time for a "Western VA Brewery Field Trip" this last Saturday. Total mileage was ~367 miles from my place in Ashburn, VA. The Strasburg charger is about 60 miles from my place, so I topped off to about 245 rated miles there. The route continued down to Staunton for 2 stops at local breweries, then on to Afton (south on I-81 then 64 East about halfway to Charlottesville), where we hit two more.
That's a 240+ mile round trip back to the supercharger. With the speed limits along that corridor (70MPH, traffic does 80), some elevation change, and colder weather, that's a non-starter for a single charge.
Fortunately, there's a NEMA 14-50 in Staunton in the public lot right behind the breweries there. I was able plug in for ~2.5 hours and put about 70 miles back in to the pack. That allowed me to make it back with about 35 miles of range to spare.
Had there been a supercharger in Lexington, the whole trip would have been a no-brainer. I would have saved the initial ~40 minute top-off in Strasburg, and not have had to hope the stall adjacent to that single 14-50 was free in Staunton.
While Lexington is only ~110 miles from the Strasburg supercharger, it's at the junction of 64, so I think it's a very useful location in addition to Wytheville.
Will have to use the opening of the Lexington charger as an excuse to go hit the breweries again....
