Layers. Lots of layers. Especially if you're thin as a twig.

Baby steps on the ice, even if you have good boots. This is a rule of thumb that can help prevent slips, falls, and potential concussions.

When buying boots, waterproof them with waterproofing spray before using them. They should be sprayed and then sat outside for 24 hours.

For the love of God, buy a snowblower, if you are able to. Electric, not gas--less hassle and they run better. The EGO brand sells very good and durable snowblowers. If you can't get one this season, buy them near the tail-end of summer, earlier than that if possible. People snatch them up come fall and when they do you will be SOL.

Also, buy shovels. You should have one regular shovel (for yourself; buy more depending on how many people live with you, if any), a pusher shovel, and a sleigh shovel. Snowblower should be used if the snow exceeds 6 inches (4-5 if wet and heavy), but that's my general rule of thumb.

And finally...go sledding. Sledding is very fun on big steep hills. Even more fun with a friend!

Welcome to Maine, enjoy your first winter!
