I've done that the past 2 winters and it is very helpful, more for dirt/grass tees than for cement. If the tee pad is cleaned, then you will slip more having metal sticking out of your boots so bring 2 pairs of boots with you.
Vest is key for me. I have found that the key is keeping your torso warm (vest) with minimal layers on your arms. I keep a glove on my non throwing hand and wear nothing on my throwing hand. Get a butane hand warmer and keep it in your throwing hand pocket wrapped in a micro towel. Just keep your throwing hand in there and it will stay warm and dry and you dont have to keep taking a glove on and off. Pay the extra for the goretex boots, you will be happy you did. Nothing worse than wet/cold feet. If goretex EVER leeks, send them back and they will be replaced no questions asked.
If anyone has a better method than gorilla tape to keep your lights on in the winter, pass it on :) I dabbled with a few ideas with no success yet.
Don't forget your head! You lose an amazing amount of heat from your head. The proper head gear, hat, watch cap, balaclava, or ski mask can make all of the difference. I have layered a thin balaclava with a stocking cap over that, and a hood over everthing. Easy to adjust to different layer as you warn up or cool down.
Remember the old adage, if your hands or feet are cold, cover your head.
I'm a big believer in Under Armor Cold Gear. I wear it for all my winter sports. Mark's advice for mittens is spot-on as well. Take one off to throw then slip it back on.
The biggest advice I can give you is keep anything cotton away from your skin! No cotton socks, T-shirts, jeans without a tech garment underneath. The reason for this is the cotton will trap sweat next to your skin making you clammy and cold even if you're sweating.
Sure am glad we don't have to deal with that northern winter. Today they will be playing in shorts, sneakers, and tee shirts. Blue sky, and sunshine. Been kinda grey for a few days and now it is going to clear up and warm up. Some one should put a posting for Aces. Each day as players hit an ace, they can post it on the site. Name the course and hole. Just a thought.
