Coldest ever for me was patrolling @ The Cat in approx 2005ish. -30 w/ 90-100mph winds.coldest ive done is -23 F at tremblant on blue bird day- +4 degrees with sun not too bad. How does altitude play into it (seriously asking)?
We were stranded up top, hunkering down in the shack for 2-3 hours until they brought up a bully for the 3 of us and shut the place down.
