Here are some links to the rules and regulations on Hunting and Fishing in Massachusetts.  Know the rules before you go into the field to enjoy these sports. Respect everyone involved, the wildlife, land owners, others in the field especially those who don't know because they aren't involved with your hunting or fishing sports. 
Don't have arguments in the field even if you are correct. You can't teach unwilling people in the field.
