Take note of what Denise states - if you even drop your helmet on the ground - it's time to get a new one. Have a friend, a newbie, struggling to get all her gear together, drop her helmet on the sidewalk. We all heard the big clunk. She picked it up and put it on. I had to explain that the helmet is now no good and she'd have to buy a new one. She learned the hard way to properly take care of her helmet.

Like others, I don't buy the most expensive helmet - I like the Giro Havocs which on sale cost me around $35 - 40. If I fall or drop the helmet, don't feel so bad if I have to get a new one. Also, usually buy 2 at a tme - that way if I need a new helmet - have it handy.

Since I do land on my head on a regular basis, I usually replace helmets every 3 years (if not before). $40 is a small price for safety!!!
