biking in 1968

I bought this license plate on ebay a few days ago. I hope it's legit!

I'm posting it today because I presented on the history of 19th century bicycling earlier today at the Shaw Library, 7th Street & Rhode Island Avenue, NW.  Click here to read about event.

I know quite a bit about bicycling in the 1880s and 1890s.  But I know very little about  bicycling in the 1960s.  

Did you bike in 1968?  Were you part of a club?  Are you familiar with the Potomac Pedalers?  What were the favorite bike trails in the city?
