Hilarity! I took the MUP all the way. ~5 miles of rough & packed (from pedestrians) snow. I dropped my front tire pressure way down and it made the ride a little easier.

Eventually it started getting dark so I threw on the Light & Motion 13W halogen and pointed it downward to I could see the best track in the snow.

So this dude... He walks out onto the trail about a quarter mile ahead of me and stands there. Right dead center in the hardest & easiest to ride packed track, and he's not moving. As I get closer I see he's messing with his cell phone. He still wasn't moving so I said, "Please don't stand in my track, dude!" He looks up and he says, "Oh man I was calling the police! I thought you were a snowmobile on the bike path!"
A really REALLY quiet (and very slow) snowmobile, I guess.

So we had a good laugh. He said my light is really bright, and I even had it pointed downward. Good to know I guess.
