Sleds for babes
I am one of the few people on New England trails who took the plunge and purchased an expedition pulk. I often envy my friends with home-made sleds, for their industry and thrift, and the sleds for their light weight and downhill speed. My sled has its strengths as well, of course.
Many many of the homemades I have seen actually roll fairly easily. Obviously, the rollover hazard is an important one, especially in baby's first year. If you go homemade, work very hard to insure a stable sled, certainly with crossed bars and a tight connection to your waist. Or ski only where it is flat flat.
I haven't decided if I will spend again and get the baby seat for my pulk, but it's probably the only sled I would put him into this year either way.
