At this weekend's free Home Depot kids workshop (Saturday, March 6), they'll be making free rain gauges, which can double as snow gauges. I won't be able to attend, but I did the next best thing and built my own. I put an old bucket up against my house and at the very top wrote “&*#$ TON.” There we go, that should cover this year's snow fall.
The workshop is available to kids 5-12 and runs from 9am-noon. Call your local store to make sure they are participating.
