Ventura Headlight Guard

We were warned about a lot of potential dangers to ourselves and our bikes while en route to Alaska. One of these was flying rocks, presumably from trucks that kick them up from gravel roads. With that in mind I bought a few items I wouldn't usually be interested in for commuting. One of these was headlight guards from Ventura Motorcycle Accessories. The guard is a piece of plexiglass shaped to the headlight that attaches with velcro. $25 plus shipping. Even though it'll be light out 23 hours a day and I'm bringing a spare bulb, I figured better safe than sorry.
