The state has sent around a few flyers looking for volunteers to help them stock Atlantic salmon fry into suitable rearing waters this upcoming spring. I have done this in Vermont and think it is a pretty nice way to get outside, see some new streams and participate in a worthwhile event.

As a bonus - it is a great way to check out prospective trout destinations - you may want to stash a 3wt in the vehicle for some fishing later that day. You could tie up some fry patterns and go to a few of the locations where browns are at - you'd probably clean up
