I have a generic Bell as well. For the price, it offers a lot of vents, tested and certified protection, and decent looks. You can buy more expensive helmets, but that's up to you.
Oh yeah... What tsl said... I assumed you had 1-2 solid bike locks that you took with you... If you are in NY... I'd scoop up a NY chain and a NY lock if you don't mind the weight. At least get the U-lock if the NY chain is too unwieldy. In any case, consider locking skewers too if the bike is going to be locked outside for significant lengths of time... its nice to have a fork and both wheels on your frame when you return.
