Hmmmm - first you say that state websites are a hassle -
Then you say that if there is traffic and shoulder data they are the gold standard.
Now those would appear to be contradictory statements.

I find it odd that so many megabytes here are devoted to gear inches, tires, spokes, bar ends, etc.
When just a little time looking up easily available data would allow for much nicer riding.
Isn't that what gear inches are about - more pleasant riding up hills?
Wouldn't you think a road with 485 AADT would be more pleasant than one with 3500?
(AADT - average annual daily traffic)

Google Maps don't say a thang about AADT.
Not to mention that Google Maps can put you on closed, non-existent, private roads, too.
