This happened yesterday.
Went out the door for work 6:45 AM. Had my Giant Boulder SE P(nothing special, bought it used on eBay to keep as a knock-around bike to play with until I could afford a nice road bike) with me. I keep it inside to keep it safe from thieves (had a securely locked up Trek 800 stolen off the bike rack earlier this year). So, I carried it up the steps and out the door, then remember I left my folder inside that I needed for class after work. Left the bike leaning next to my apt. building and ran inside. I was in...for maybe 20-25 seconds TOPS. Found the folder, put it in backpack, dug around make sure I had all the papers I needed. Come outside, bike is gone.
And around here, on a college campus, 6:45 AM means the area is a ghost town. Students are all asleep. NO cars on the road. I have long open streets all around me. So I ran all around looking up and down the streets to see if I saw some ******* riding it away...and nothing. I checked behind the building, bushes, in the building's hallways...spritning back and forth, and nothing. Just poof...gone. What kind of thief is waiting around that early? Who has the ****in balls to see me jump off the bike...run inside...and still know they'd have enough time to grab and it disappear before I came back out?
It just blew my mind. Deserted, outdoor area...run inside...come back...bike is gone without a trace. Sigh. People make me sick.
