Hi there harris7.Greetings from the uk.My wife and i were lucky to have spent a week in the Rockies in Alberta a couple of years back.What a beautiful country you have to live in.Where do you live and how old are you.Id be interested to know.Anyway,in response to your post,the reason that i believe is purely and simply because i chose to.I just hope that dont seem too illogical.All the best.Chris
