1st - I noticed this was your very first post - so, Welcome Aboard Islandgirlaus! You didn't list your state (or country) in your profile. So, you might consider jumping over to Sub-Forum: Select Your Area.... for information (i.e., clubs, hunts, finds, legends, maps, etc.) directly related to your state (or country). You might also consider adding your state (or country) to your displayed profile (SETTINGS -> EDIT PROFILE) - members may have more success helping you (your location may help, etc.)...
