Everyone tells me I need to walk: doctors, family, friends, the AARP. I could probably think of others. So, I've been walking and find I like it. I know, I know, everyone told me that, too. Three things make it fun: One, my SuperDog Sadie; Two, the glorious and varied Colorado weather; and Three, the cute little pink digital camera Keith and Mary gave me. I've been taking photos randomly as the interest strikes me, and now have files of clouds, flowers, shadows, signs and feet. And manhole covers.
