I forgot my boots. The first TWO times I went. Luckily I remembered soon enough to turn around and not waste too much time, but ... really??
Reminds me of one day last year I blanked getting my boot bag ready and left my boot liners sitting on the floor next to the boot bag as I packed up my boots and everything else Drove to the mountain and then realized "what have I done" Skiing in boots without the liners does not work. Luckily only an hour drive home. So, two hours later I was back and ready to ski.
