Hi guys!!
Thank you so much for your suggestions and ideas!! I usually study very well my bike travel (for Australia I studied for 7 months and TransEurope, from Firenze to Nordkapp almost 1 year!), this year, as I said, I have a brand that supported me but the bad aspect is that this partnership has change my plans without more time in programing...I had to go to Iceland not in US on 2013

So..I'm very very happy to do coast to coast but this kind of travel needs a good organization.

For the night I have a tent and a sleepingbag so is not so important for me, camping or Hotel/B&B is always ok.

Hi! I have decided to do coast to coast so..I think Denver is not the right place to start my travel

Nevada 50 was in my mind

but I hate extreme hot and is not a good idea.. about NYC and the way to go there, if I start from Oregon I use the first section of TransAm, Yellowstone and Grand Teton and after, Wyoming, Nebraska and Iowa until Muscatine. From Muscatine a part of Northern Tier until Ashtabula, leave NT and Pennsylvania until NYC. What do you think?
In case of north starting I would like to start from Florence Oregon, (same name of my city!). I will looking for flights from NYC to Portland..
So..do you know some good routes in Wyoming, Nebraska and Iowa?? Same height of Yellowstone and GTeton of course..
