I saw that article. Kind of what got me thinking about this thread.
Plus today - with all the stuck cars and trucks around the area - I considered stopping for a few of them - but honestly - I didnt feel like "dealing" with the chain thing - heavy, dirty, messy, cold, wet - was busy and on a time schedule anyhow - but I thought about it at least.
I probably would have tugged a few of them if I had a strap. Less mess - less weight.
