In my attempt to keep using the Fargo in almost everyday settings, I recently installed a Wald basket. I was hesitant at first, but after a couple weeks I am sold. I really wish I would've installed one sooner.
The basket is pretty light for being made out of steel, and is pretty handy when you have something to just toss in. For a bag, an old military surplus sack fits the basket perfectly, with room to spare. Spare enough room for a couple bottles of beer in the bag, and a sixer to boot.
With one of these baskets, be sure to carry a lot of straps or bungee cords to secure your cargo. Pretty easy setup for everyday adventures, and made in Kentucky as well. Perfect.
