There is a walkway, a berm really, at the back end of the small Windham Connecticut airport. Walking here gives you a different perspective since you are above the river and marshes.
Looking down you can photograph a fairly wide section of the river. The Willamantic reservoir can be viewed from the end of the berm.
The last week in December, in New England no less, and I watched a few people fishing out in the river. When winter finally comes I hope it’s not pay back for days like this.
