Got it. Biking to work yesterday and got quite the work out. The snow had melted and it was a cement ride. But today school's closed due to the storm--tomorrow I'll have some real snow! I brought my bike into the classroom to keep it warm. (Plastic bags on floor so the custodians don't have an extra mess.) The night before my old cheap panniers had strap issues, got caught up in the hub during the ride home--had to toss them. So I've been riding with a big backpack (not pleasant) and now must get new panniers. This is getting a tad expensive--but they are good investments in health and planet.
