Went fishing out of Gloucester one May, we had a string of really warm days with the day I went in the 80s so just wore a short sleeve shirt, froze my butt off fishing that day.
Only time I had water in my basement was in December one year where it was really cold for a good stretch then it rained hard, rain just stayed on top of the frozen ground and came in under my door. I waterproofed it after that and that was the last and only time.
Mybe he just likes to ride his mower. I had an old guy for a neighbor, he cut his lawn frequently, not sure if it was every 3 days but it was more than I did.
