that was very nasty. There is something embarassing and almost exhilerating when you recognise one of your wheels passing you on the hiway. Unlike Elizabeth's scenareos, mine was due to someone trying to steal the then expensive aloy wheel on my boat trailer. No one was hit in the oncoming direction it crossed, and i was able to follow its path through long grass and retrieve it. To this day I don't know how it got through a fence or jumped it (best bet).
