Bob, I don't use TP and when I drink my coffee, I throw coffee grits in my teeth and then pour boiling water through my teeth-strainer. Sometimes I eat the grits after. J/K, I forgot the TP and had to beg Mark for some.
Trevor, I got my plastic boots 10 years ago and they still work great. If I'm on snow, I always use them. Here is why: I've seen fit climbers with very cold feet turn around on Shasta and similar mountains. They would have summited if they had warmer boots. Most people can climb it with leather, but a few have problems with their foot circulation or the low temperature causing "unbearable" pain in their toes. If you go with leather, take time to make sure you have room for circulation to your toes, error to the side of having your legs too warm on summit day, be careful about too thick of socks, try walking in the boots on a treadmill at a 15 degree angle at 2 MPH for 30 minutes.
Trevor, are you headed up there this summer?
