Katie - hang in there... and you're right, staying at goal for the summer months with as much vacationing as you've been doing I think is a phenomenal feat.
Melissa - Great to hear you're getting back to walking. It's the only thing that really does it for me. I justs can't seem to commit to a gym, and forget at home stuff. And while my hubby half the time has to push me out of bed to walk in the mornings... I know it has been the key to losing the weight as consistenly as I have.
So hooray for you. What kind of pace do you keep? How long a walk is comfortable? Do you do any hill work (ugh)? I try to walk 3x a week. Monday with my Leggers group at track (1hr), Thursday morning with a friend 1/2 - 45min, and Saturdays with the Leggers walking group (this varies but we'll be up to 4 miles this week).
