[Talk-us-massachusetts] Quality of US Large Scale Imagery

It seems to me that the quality of the US Large Scale Imagery has
deteriorated in the last month or so.
Imagery at the high zoom levels seems much murkier.
I used to like to use it because it always seemed to be taken in the winter
without leaf cover; not so now.
Also, it's loading very slowly.

Judging from building constructions in Bedford, the imagery is about the
same date as Bing.
I've never figured out how to check the date of the imagery. Can anyone
help me?

I'm continuing my quest to review all un-named residential roads in MA
against the 2015 TIGER data. I did Aquinnah on Martha's Vineyard over the
last couple of days. I'm working alphabetically, should be done in a couple
of years. It would go a lot quicker if I didn't stop to add a few amenities
along the way.
