Dear CGN Member,
I recommend you travel to Moncton, primarily in the Coles island area. It's close to you and the amount of deer and public land to hunt on is some of the best in the province, and the maritimes. Given your time limits I think this is the greatest ratio of success you'll have.
If you can brave it you can sleep in tents on the public land, contact NB's DNR for more information. Look for the area where the cabins are on public land.
I would suggest picking up a climbing tree stand, if I was going to suggest one to a newbie I'd recommend a "gorilla" type which can be purchased at wally mart or crappytire. When you get into the area, there are several cut lines, power lines, and gas lines in the area that offer great shooting lanes. Simply locate a stream or crossing with several deer tracks and select a tree that will hold your body weight and enable you to get up approx 17ft preferably down wind.
Whitetails in NB can be quite large in size and to limit your need to trail after a kill I would suggest using a centerfire with caliber above .243. Remember to dress warm and pack a thermos. You must wear blaze orange hat and vest or jacket.
Oh, to get blood out of clothing use a bar of lye soap before putting your laundry into the washing machine. They can be picked up at most department stores. It cleans it up quickly and completely.
Hope this helps you,
J
