Woo! Good for you! Snow biking is so satisfying because it feels like this huge accomplishment when you safely arrive at your destination. I won't pretend I *enjoyed* snow biking when I lived in Massachusetts, but it did make for some of my most triumphant-feeling rides -- after I peeled my hands off my handlebars, that is. I found that you're right: Hanging on for dear life doesn't actually help, even though it's instinctual. Another thing I learned was to not worry what the rear of the bike is doing so much and focus on keeping control of the front of the bike. If the back slides around a bit, that's OK, as long as you keep moving forward and have the front wheel in control. Good luck with the continued riding and I hope you have many wonderful, uplifting winter rides!
