I was wondering if it is to late to get into this Deer Hunting Contest? if not do i have to make my own team up or can i join a team an what are the rules?

You're ohhhhh......about 4 months late on getting in the contest, in fact it's winding down as we speak.
The rules and everything are on the contest forum.
New teams will be selected next year, and I'm sure there will be members needed to fill gaps as people come and go.
Keep your eyes peeled this summer for the contest threads to start.
