Once a year, I guess Downtown Los Angeles closes its streets to normal traffic for several hours and opens it up to people who want to bike, walk, skate, whatever.  This was a few months back, and we were able to get a good group of friends together and participate.  We had such a great day.  Even Stevie tagged along and he did awesome!  He was perfectly content riding for about 8 miles.  It was such an awesome day and a very well organized event.  I hope we do it again next year!
