Albuquerque has both and they are both well marked. Except in one instant they don't really share the same "space". They are also in the process right now (Go ABQ) of marking all the bike routes and posting share the road signs and no parking in the bike lane signs! This being said: due to the torrential rains we had while I was out of town, the bike lane in some areas is full of sand and debris and very dangerous to ride in. Several commuters have reported it to the city and as of Fri they still hadn't done anything. Due to it being so unsafe I ride in the car lane just to the left of the white line and have had several cars try to "crowd" me back into "my" lane. I'm praying that New Mexico becomes the next state to pass the 3 foot law.
As for riding them: I've ridden both the bike paths and the bike lanes/routes. Depending on where I"m going and what I"m trying to accomplish, the bike lane/route is my preferred method of travel but I know some people don't like "urban commando" biking!
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
