I, like maybe / probably most bike owners, have my bike parked in the garage ( shed ) next to / under / near a LOT OF OTHER shit.
I carefully manouvre it into the very best spot, making sure that when the stand is sprung and the bike flops into position, it makes zero contact with STUFF.
I then place a thick doona cover over it to keep the dust / bugs / aliens and anything else that cares to f**k with me and my bike at bay.
This morning I was getting a pair of boots from the shelf above and dislodged a neighbouring heavy soled trekking boot away from its spot and down .... onto the bikes fuel tank !
The noise was like banging a hollow drum HARD with a soft hammer ...
I nearly had heart failure !
Thankfully, zero damage.
Stories ?
In my previous residence (to my Melbourne digs), when I lived overseas in Toronto (Canada), I had a condo in a 3-story condo building. Out back were parking spots, and my condo came with one uncovered and one semi-covered parking spot. It was semi-covered because it was a row of garages with open fronts, and owners had the option of installing a garage door to close it in completely. I would park the car in the uncovered spot and the bike in the semi-covered spot. But to be careful, I installed a garage door, to be able to close in and lock the bike into the spot. There was no heating or electrical supply to this semi-covered spot, so I always stored the bike during winter at a local service shop (below zero necessitates heated lock up). But otherwise, here was a row of semi-covered spots with one little spot with a garage door. To be careful. Yep, so thieves come about one time, obviously thinking that one semi-covered spot with a garage door must be hiding something, so they gain access. They find my hog in there, but it is both in the garage behind a door and tied with a big chain to a post. So they take a rock, smashing the spark plugs. Just the spark plugs. Then they left the condo parking garage, not bothering to touch the cars in the garages without garage doors, but breaking the windows of the cars in the open garages. I miss those spark plugs.
