So on my way home, I realized that I needed to stop by the feed store and grab some cat food. It was pretty close to closing time, so I didn't have time to run and grab the car forcing me to make do with what I had available.

I keep a diamond shaped bungee net on my rack, and had my lunch bag tied down with it(It's small). I was able to lay the 30 lb bag of cat food over the the rack with the lunch on top and get it secured, bu the load shifted a lot and actually slid sideways off the rack. I didn't catch it for a mile or so, but I had a big ass bag of food hanging inches from my rear deraileur, being supported by a single cheap bungee hook.

Any better solutions for stuff like this? The bungee net is good for a small bag of groceries, but because of it's size and shape isn't great for the occasional wide load(as this was).
