I just now realized that I ride by my families favorite grocery store to get ready made meals. I currently have no place to stow any type of groceries and thought, "Why not slap a rack on the back and get a soft side cooler with a bungee the I can bring dinner home at night." So, having never even thought of slapping a rack on my bike I am looking for suggestions and things to look out for.

I have a 26" wheel MTB with disk brakes and braze-ons. I have no aspirations for panniers or anything at this time but may consider it in the future.

Thoughts?

TIA
