Do you live in miami ? Well, if you do and you're interested in meeting up with other young cyclist come and join and participate at http://criticalmass.meetup.com/40/ These meet-ups are fun and great to meet people. Most ride are nice and relaxing. We tend to cruise at low speeds so everyone is comfortable but the rides are long and great exercise.
Me and my friend are trying to start a more high speed meet up probably more towards the evening time. Something fun to learn things off of each other on the weekly basis. If you'd like to be a part of this just come out to our next ride.
