I started skiing later in life than the posters above... I was 18 yo but I'd spent many years water skiing before hitting the frozen version. As I said, I was 18 so my memory of that day is still there.... What I remember was buying a ticket for $17 on a day where the snow was puking down and making my way to the bunny slope that was serviced by a poma (J-bar) surface lift. Through some miracle, I managed to stay on that lift to the top and was faced with the daunting task of attempting to skiing down what I perceived to be a very steep slope (remember, I said it was a bunny slope). Anyway, I managed to ski for 50 yards before fear of the speed I was travelling at caused me to execute a butt arrest. I did this several times more before arriving at the bottom of the slope. I tried to go back up the J-bar but fell so I spent the next hour trudging up-slope a bit and practising stopping (something I suppose I should have worked out before my first attempt up the lift).
Anyway, I managed to get the hang of it (or so I thought) and even succeeded in making runs down the bunny slope without falls that afternoon. As I mentioned at the start, the snow was puking down and the cheap depot parka I was wearing had lots of loose threads. When I finished, the snow had stuck to the threads and created a rather interesting pom-pom affect.
All in all, it was an enjoyable day albeit very tiring... the first beer after skiing didn't even touch the sides
27 years later, the first beer after a day on the slopes is still just as satisfying.
