Thanks for the replies.
Definitely not doing my proposed route then- Thanks Miller!
My biggest issue with riding the TransAm from E->W starting at the end of April is timing... I don't really want to wait until the end of April to go... I've been trying to select a route that would allow me to start early to mid March.
I suppose the more general question here then is what do you advise I do if we want to set out that early?
(Actually live in the UK by the way )
I don't know if this matters to you but yet another consideration is that there probably won't be very many leaves on the trees in March and early April, which IMO greatly detracts from the views. You also won't encounter many other riders with a March start.
If you really wanted to leave earlier you could cross America diagonally and start in Key West, Florida, rejoin the TransAm in Virginia, and end in the northwest corner of Washington (or Astoria, OR). See Jeff Arnim's Journal below...
