Years ago when I was young and stupid I'd think nothing of sitting there whilst frost built up on my fishing suit (one piece ski suit), or wiping rod rings with glycerene in a vain attempt at stopping them freezing up trapping the line.
Heck, I even fished Roundhay Park Lake in my youth - the water level had been dropped at the time to work on the dam wall, and we were fishing having broken the ice, covered in white frost, barely moving so not to break the ice on us, and watching swing tips waiting for that one solitary twitch, when the local copper came and gave us both a tap and told us to "gerrof 'ome ya daft sods" - apparently someone had called the 'parky' to report us lol
