Yes, I put a handle on it.
I went down to the local hardware store, and in the electrical section purchased a piece of 1/2" or 3/4" plastic conduit about 8" long with a bend in it.
Then go to your local motorcycle store and buy a "soft loop" tie down extension. This is a piece of nylon webbing about 18" long with a loop on either end. it is very strong. Run this through the bent piece of conduit, and then connect the 2 loops to the hook on the end of the sno bunje. The result is a very strong handle that is good to pull on. Total cost about $4.
Fortunately I have not gotten badly stuck enough to need to use my new snow bunje yet.
