My brother and I caught their concert in Claremont, NH on 8/6.
That's 100 miles from the home locale over roads that are somewhere
between Rte. 19 on the Big Island and Rte 550 on Kauai (but not as
scenic).
Average speed over the route was about 40 mph. So we wound up taking
two days off from work to do the trip and made a few stops en route.

(Yeah, Cambridge Mass. would have been closer, but I hate city traffic.)

Claremont is on the border between New Hampshire and Vermont and about
50 miles north of the Massachusetts line. They still drew around 300
for the
concert -- on one of the hottest nights in recent memory. The folks up
there
have respect for good music.

Not much to say about the show itself except "WOW!". What a great time!
