Where o' where to put your stickers?

Says Little Joe -

Hey Gang, I wanted to thank you for the sticker you sent a while back! I've been spreading the message around to my family and friends, (and in the process convinced a bunch of them to go mountain biking and commuting with me as well as do a triathlon with me!) I just wanted to share some shots of my personal helmet, at rest. Keep up the great work. Little Joe
