Take a Brommie
Hope you have a fabulous time - my folks are very fond of that part of the world and I think I'm going to have to visit at some point now I know I won't get the clean gloves and warm tongs treatment...
You should visit, everyone should visit Colorado and Boulder in particular. When I cycled across America I went from Denver to Boulder then trough the mountains from here. There are some fantastic routes. Motorists in the hills, in my experience are considerate to cyclist, maybe a little impatient at times but the roads are wide and gradients not very steep. I know a lot of people in this area now as the company I work for is based in Denver. At some point I hope to take a bike and do some of the Rocky Mountain CC Randonees.
So Charlotte, you want to meet me at Heathrow tomorrow lunchtime and loan me your Brommie for the week ? Only kidding !!
