You don't need a lot of specialized gear to head out the door - just a helmet. Get your own so you can go and ride! A water bottle is way better than a camelback (IMHO) and gives a little more freedom.

When we were 12, and we used to call our friends on the phone, and our friends would be like, "why don't you come over?" we thought nothing of hopping on our bikes and riding over. So you just have to be twelve sometimes.
