marcham, you are either more interpid than I am, or else far luckier.
I have tried to ride to Vancouver three times:
June 2006, I rode from Toronto via Denver to Vancouver, back via Edmonton.
I attended my son's wedding and had a wonderful time both ways.
May 2010, I tried to ride from Sarasota to Vancouver, but was
absolutely assaulted by crosswinds in Arizona, to I ran for home.
Good thing I did, because a friend of mine, riding a CADILLAC,
was blown from one lane to another of the highway in Nevada (part of my route).
June 2010, I tried to ride from Sarasota to Vancouver, but encountered
snow in Colorado and learned I would have 600 miles of it, so I went home again.
I thought that Colorado and Utah were downright MEAN to entertain snow,
in the middle of JUNE, I ask you, when I was planning to ride across them!
I would not try to ride from Ottawa to Vancouver in April.
You are a better man than I, as is Gunga Din.
