Thanks Doug! That is great news. Obviously any small multipurpose tool like this is a huge compromise. If I expect a better than normal chance of getting stuck someplace, I'm going to bring a heck a lot more then even just a real shovel. How about a high lift jack for starters! Anyways, sounds like this will be the perfect "just in case" device, and can be supplemented for longer trips or rougher circumstances.
Frankly, if we're doing any long wintery trips I'd rather not take my girlfriends car anyways.
