So I'm 149 lb now (started @ 165 lb, yippy!), and I walk to work pretty much everyday, 20 min each way. MFP says I burn about 74 calories each way. From living in Canada, I KNOW that walking in snow (especially soft snow) takes much more energy than walking on clear pavement. So how can I track this? Anyone know? I know maybe it's a bit ambiguous since "snow" can differ from a few inches to a few feet, but any sort of estimation might help
