This has been playing on my mind all afternoon and was wondering what you would have done.
I took my kids to the park and on leaving I noticed two bikes in the new bike park section that has loose stones as a base.
One of the bikes (Triumph triple) had its side stand buried about an inch but looked stable. The other, a Honda (think old CBR) was on its side. From walking past you could see the side stand had sunk tipping the bike over.
What would you have done? I did nothing as I was worried the owners would see me and think I pushed it over, trying to steal it, etc. I feel bad for just leaving it but did not want to start getting into blame games, etc..
