It was supposed to be well below 0F when I went skiing last Saturday...I was disappointed, I don't trust the accuracy of the temp sensor in my car but it said 3F when I arrived Friday night and 4F when I left the condo around 7:30am.
Not very windy at my place, but it was howling pretty good at the mountain (20-30mph with some gustiness to boot) and the main lift wasn't running...I did my homework and verified before leaving work that the lift was running on Friday, which was definitely a windier day. But, the problem was the wind was blowing ACROSS the lift line on Saturday and making the chairs swing wildly, whereas it blew straight DOWN it Friday and that was not a problem.
I found some little stashes of untracked snow off a smaller lift (cannot call it powder on the East Coast) and had some fun, but I made a big mistake by not going on Sunday, instead...a bit warmer and much less windy then. I figured the lifts would run Saturday if they managed to run them Friday and that it wouldn't be too crowded because of the cold, bad gamble on my part. Couldn't ski both days because I had too much work to do and was in the office all day Sunday!
I didn't get to experience how my engine cranked as I used the remote starter, but around 0F is really nothing at all as far as cold. I'd like to catch a night below -20F and see how it cranks with 0W30...not that I ever had a serious problem with 5W30 at such temps.
