Fantastic Pix.

I am amazed they allowed you so low. I thought there was a height limit of
3,000 or
something like that.

No, FAR 91.119b sets the minimum altitude in congested areas as 1,000' above
the highest obstacle within 2,000' horizontally.

That brings to mind a caveat for flying a Boston city tour. Occasionally a
controller will tell you to maintain 1,000 (especially if you've been handed
off to a helicopter controller, which sometimes happens for a city tour).
You're required to stay 1,000' above obstacles even if instructed otherwise
by ATC; so it's up to you to say "Unable 1,000 due to required obstacle
clearance; request 1,200".
