Michele, enjoy your trip. Yellowstone is incredible. Make sure you go to the Grand Canyon of Yellowstone. To me, it was more beautiful than the real Grand Canyon. There's a gigantic waterfall and if the light hits it right, there's a rainbow over the canyon. I have an incredible picture of it. Also you can "hike" to the bottom of the falls. There are many stairs. The hike down was a breeze. Going back up just made my asthma mad but it was still worth it.
wenonah, welcome to the board and enjoy the WATP videos. They aren't so strenuous that you quit after a few weeks. I've been going since January pretty much everyday. In March is when I bumped it from 2 miles to 3 miles (and above).
I did my 2 mile walk and the 1 mile jog this morning. DH and going to go hiking and add another couple miles to those three. I just love summer and being outdoors but I can't give up Leslie's workout - so I just do more and sometimes nap in the afternoon.
