A moose guard?

As I contemplate that I will be selling Miss Doozie at some point in the "relatively" near future (within the year unless God leads me differently), I took a look at one of the primary broker sites for buying and selling Blue Birds, "Buy Bye Blue Bird".

It has a custom "Moose guard", installed in preparation for a trip to Alaska on which the owner wanted to be prepared in case there were any moose who chose to trot out in front...
