@annejefferson My Dad and his brother grew up in Ipswich, Massachusetts in the early 20th century. Dad had a few photos of cutting ice from lakes to store in ice houses for summer use. Our family would spend Christmas in Ipswich on occasion. Cousins had a farm pond we would skate on. Photo is of Niagara Falls in early January about 1960.

@Anthro A winter view from early 60's.

@futurebird I worked in a naval shipyard here in the US. I was a machinist and all measurements were in .001 to .0001 inches. Yes, I wish the US switched to SI many years ago.
