"Not too close to the edge!"

I have spent the better part of the last two days saying that, as huge parts of the Grand Canyon rim trails have no railings.  The Canyon is...well, I guess I don't have the words to adaquetly describe it.  We were out all morning doing ranger lead programs and walking the rim trails.  We came "home" for lunch and a rest and we are heading out again to hike a ways into the canyon.   Everyone is sad to leave tomorrow, but we are happy that we are heading home.  We are off to Mesa Verde National Park in Colorado tomorrow.  Can't believe we will be home in less than 2 weeks.  Not looking forward to all the housework, but very glad to be coming home to friends!
