HI there...new joiner here. And I am actually considering a 13 mile one-way commute to work. Am I crazy? My husband commutes 12 miles one-way, and loves it, although he only does it during the spring and summer...washington winters are WAY too cold and rainy to commute that far! I figure I get my cardio done, so won't have to stop by the gym so often; it's a no-lose situation! Or a big lose situation for my thighs...however you want to look at it!
