Parts of the basement floor get a couple of inches of water once every few years.
One of those times was what people described as the 100 year flood back in the fall of 1996, which put ten feet of water in the MBTA subway and three inches in our basement. Another time was a year or two ago.
The next time (we are told) could be Saturday night. Katherine says it's not my fault, the bike was already in the basement, but I wonder.
The basement has been further cleaned, and more wood blocks cut in honor of the possible coming event.
