walking is great, but so weather dependent. and early mornings....meep. sounds like you've found a great option.

i've organized my working out days so that i only have to wake up at 5am one day a week for working out...i'm willing to sacrifice weekend days if only to avoid that. ack. but if i wait until i get home it will never happen. heh.

if only i could set up a ski machine in front of my computer at work. all that time on the phone i could be skiiing. ;)
