I was trying a new method of keeping up with my e-mail notices. I was filing them under "new..." until I had a chance to go back and respond; the problem was I forgot I'd done that. I came across the one notifying of your 03/05/10 Wounded Warrior blog.
Well, you certainly don't have to worry about the snow keeping you from exercising now; if anything, you've probably got to time your walking to when the sun's just coming up or when it's going down.

Though you haven't been active on the message boards or been posting on your activity feed, I do hope you've been putting the nutrition and fitness tracker to use. And, if you haven't been active on the site, when you read this, I hope you'll be encouraged to start again.
