Are you seriously bored? January can be a drab time because of the chill, but don't let that put a damper in your spirits - even though you can't swim, you can KAYAK! Just as fun (if not more so) than swimming, kayaking is relatively safe, loads of fun, and GREAT excersize. I know that was on your rezzie list - to get more of that stuff...excersize ;)
Check out Kayak Rocky Point for all your kayak rental/purchasing needs - they have those cool pedal kayaks as well as traditional paddle ones!
