I love my geek.

He's building a light system for his bike. This has involved countless trips to hardware stores, online purchase of battery and light bulbs, dissection of storebought electrical cables, purchase of a Dremmel and a soldering iron (useful things to have around the house, no?)... He's in the home stretch of wiring before he can attach the thing to his bike. He searched everywhere for a box of the right size and shape to house the battery and aim the rear blinky light. He sacrificed a wooden ruler because it's just the right shape for mounting the two headlights. I'm impressed with his perseverence. All this so he can continue to make the 20-mile roundtrip to work even as the year gets colder (and darker).
