You don't have to purchase a license to fish in Michigan this weekend (June 13-14, 2009). Fishing rules and regulations still apply. The free fishing weekend is a great way to introduce new anglers to the fun of fishing without going all out and purchasing a license. If you do decide to buy a license you can also do that online via the Michigan DNR.
I took my son fishing for the first time yesterday and even though we didn't catch any "keepers" he is ready to go back and do it again. Fishing is just a nice and relaxing activity with an added bonus of providing a meal if you're lucky enough.
