Ah it's just going to rust eventually even with Thorns rust proofing, wouldn't fancy being buried with a Crabon or aluminum bike
We'll also need to bury a bike mechanic with his/her tools then...I mean what else are you going to do unless nothing breaks in the Eternal Cycling Plains :p
On an aside, a picture of the first owner of a frame the manfriend has, now long dead, led to a discussion on what happens to our goods when we die and who would get what. As our bikes will, if treated well, survive us. That which doesn't live, cannot die to get a tad philosophical on the Friday night.
Maybe you just want to get buried with your bike cos you don't want others to have it
