1st - Noticed this is your very first post - so, Welcome Aboard! You didn't list your state (or country) in your profile. So, you might consider jumping over to Sub-Forums: Select Your Area.... and selecting location information (i.e., clubs, hunts, finds, legends, maps, etc.) directly related to your state (or country).
You might consider leaving a post on Sub-Forums: Massachusetts with a bit more information on exactly what you are looking for...
