stolen 2007 Trek

I went to get a slice of pizza at Pagliacci in the U District (4529 University Way NE, Seattle, WA 98105). I locked my bike to a street post sign and went in for about 15 minutes. When I came out it was gone. This was my dad's bike who passed away and it means a lot to me. A reward will be offered if found. It is a black Trek 3700. It had 3 chain settings and 7 gears. It had a blinking light attached to the back for night riding. Unique traits - On the back spoke there is a long rectangular sticker that reads MOTORLESS CITY BICYCLE COMPANY.
