I've got to object to the comments about hunting without a dog.
I know that a good dog will help out considerably, but I think 75% of people out there think the dog will hunt out of instinct, and never train them. I get a little tired of hearing people yell for their dog, or watch the dog flush birds out of range of anyone in the fields.
I hunt without a dog. Last year, I did terrible. The year before, I got my daily limit twice. I do well enough, and usually better than those with dogs (not challenging anyone).
You just have to go where the birds are - the swamps, thorns and muck. The birds don't seem to read field and stream, so they don't know what "pheasanty" cover is supposed to look like.
Check out the WMA page off of the Mass Wildlife site, to find stocked pheasant areas.
