We hiked up the main trail of Great Blue Hill (635 feet elevation--believe it or not, one of the highest places on the East Coast) in about a half hour.
There is an observation tower at the top.
From there, you can observe...smog.
Oh, wait, if you squint you can see Boston!
It has been Hazy Hot and Humid these days.
(Inside it was dark and cool(er))
We hurried down, to beat the sunset!
