Organized City Bike Rides

I was just thinking about the next organized bike ride we'll do and was doing some quick research and found the following:

New York: http://www.bikenewyork.org/ Bike in all 5 Boros - 42 miles (first Sunday in May - 45,000)

Austin to Shiner: http://www.shinerbash.com/ Great Austin to Shiner Pedal - 90 miles, okay not a City ride, but one in Austin to a brewery is worth noting. (first Sundy in May - 1,500)

Chicago: http://www.bikethedrive.org/ Lakeshore Drive is shut down - 30 miles (last Sunday in May - 20,000)

Montreal: http://www.velo.qc.ca/feria/index_e.php Not a lot of information (Early June)

Portland: http://www.providence.org/bridgepedal/ Bridge Pedal Second Sunday in August - 18,000

Los Angeles: http://la-bike.org/events/los_angeles_river_ride.html River Ride June 8 (thanks Jake!)

San Diego: http://www.bikethebay.net/site3.aspx Bike the Bay - (September 7th, 2,000 riders)

Baltimore: http://onelesscar.org/ Puts on Tour De Port - (First Sunday in October - 1,500)

Long Beach: http://www.runlongbeach.com/Top_Nav/bikef235.htm Marathon route (Second Sunday in October - 26 miles)

Round Rock, TX: http://www.roundrocktexas.gov/home/index.asp?page=635, special exception for a Texas Ride - third Saturday in October

I know these folks have rides, but they don't seem to do advance notice for them...(for anyone reading this, tell your local ride organizer to make a website that works 365 days a year).
