Have just discovered (thanks to my hubbie - I really don't have time to think recreation this month) that Google Maps has a great feature (can it be new? or maybe we just never noticed it before) that shows bike routes anywhere in the country. Go to Google.com, click on Maps along the top left corner, then when you see the USA map, open the More options in the top right corner and click Bicycling. Then start drilling down anywhere in the country. I experimented with NLV first and it seems that the light green lines are bike-friendly/bike-lane streets and the dark green lines are dedicated bike trails. I also discovered that Google will give directions between two points using either car, public transportation, walking or bicycling. And you can adjust these little maps if you want to go by an alternate route.
Using this knowledge I explored other trails and areas I am familiar with. Everything rings true unless a route has two designations (i.e. path in a state or national park) and in those cases the bicycle designation seems to take second place (doesn't show on the map). No matter, this will be a great first step in planning any future trips.
