Where to go?
Why not see North Americ on your m/c? I am sure you have not seen everything in the USA or Canada.
With your $3000 you could use the Motorcycle Travel Network and stay 200 nights in the homes of other MTN hosts. MTN is located in 46 states and Canada.
You would be meeting other motorcyclists that could tell you what in their area is worth seeing what roads to ride on your motorcycle.
