I'll be honest. I made a list of every WMA within 90 minutes of where I lived, marked them on a gazeteer and spent the next few years stopping at least once at each of them different times through the year. I have yet to find one that I thought was worth hunting. There is one in Exeter or Brentwood that NHFand G specifically mentions how many waterfowl are around. NH Audobon has posted signs and built trails through it. I've been there 20 times and seen 2 ducks and probably 5 hunters.
There certainly are some good ones for hunting ducks, but I think the F and G write-ups are way overblown.
There's one in my town that I go to probably once a week to run the dog, F and G lists partridge as being there. I'm more apt to believe there is a mountain lion living there then partridge.
