Actually, I DO know how this can happen! I parked my dune buggy trailer in the back corner of our yard for 8 years and neglected the weeds around it for that long. They grew up around the wheels and axle and engulfed them completely. It took me about four hours to cut the trailer loose! My weeds didn't get as big as this "tree" did around this bike, though! Mine got about 4" diameter at the base and pushed through the 3/4" ply floor of the trailer, then lifted one side about 6" off the ground.
But, I would never let this happen to a nice bike like this one once was! My trailer is already back in good shape! It would take days with a sawzall and a dremel tool to cut this bike out.
