d-town to south bay to ferry and back...

I did a 30 miler yesterday ALL of it on flat smooth bike paths and decent bike lanes...I've been riding in SD for so many years and yet only did this cool ride for the first time yesterday. I started d-town and headed towards national city on harbor drive (wait here is a link to perfect directions http://www.efgh.com/bike/rsdbay.htm)...I was having so much fun I got distracted and went the wrong way for some 5 miles so I ended up with 30+ miles. This is a great ride for a nice cardio workout. Very little need to stop and you can keep a nice steady pace throughout.
