Contemplating a Bicycle

I've been volunteering and maintenancing roofs this past month and certain places in Brooklyn are next to impossible to reach and walking is the next best option... What about a bike!? It's super environmental and it's exactly what I'm supposed to use as my transportation except I can think of a million excuses why not to do it. NYC drivers is just one to name and I'm not an amazing bike rider, just not yet but it's a commitment and I'm not sure if I'm a NYC bike rider yet!? Maybe I'll ask for a bike for my birthday!?! And maybe some health insurance to go along with it! Lol
