RE: Snowshoe considerations
Buffy, some good suggestions, but a couple of points, the championships wasn' t decided on 10, but on 30 targets, 20 Friday and 10 Sunday. Not ideal, but most local shoots are 30, at least around here.
You can very easily have hard/easy course within the same distances, even if target for target the distances are identicle they can be drastically different in difficulty due to hills, angles, targets, tricks to make distance estimation hard etc.
