Fly fishing Roaring RIver Missouri.?

I was wondering if I could buy my daily trout tag online a few days before I go to the river. When I get ther the shop that sells them will be closed for the day and I can’t get to the shop in the morning before the the fishing starts and I would really want to fish as soon as it starts.

get one online at missouririvers.com
