US, "Rust Belt" industrial state in the southern Great Lakes. We have, as a rule, horrible roads in my area, which is the 'burbs of the state's largest city. Outstate, where there are fewer roads with much less traffic load, they seem to be better.

OTOH, we have a great regional MUP system, due to Rails to Trails, and most communities here also have great "safety paths" which are legal to ride on as well.

I've been mostly on a hybrid and mt. bike kick lately, but when riding my road bike and my new tri-bike (which alas has seen little action) I've taken to riding around a brand new shopping center with great pavement in the early am hours (3-4-5 am) when it's essentially deserted. Smooth pavement, great dimensions for doing HIIT training and cornering, etc.
