Well, that's something that would never get any play in the South.
What a fun idea for snowy regions, though; you are so clever! I know you'll love having an accurate scale to measure your snowfall.
Ha! Definitely a regional craft. Maybe there's some way to make a mailbox or something into a humidity meter?
I don't have a clothes line, but I was thinking a snow gauge would be handy ( mostly because everyone asks me how much snow we have and I never really have a good idea.) Maybe I'll attach mine to that wood shed you've inspired me to make.
