Well, I have to admit I've "been there, done that"...well, sorta anyway.
The year, 1990, and movin' from our first condo to our first house.
Except, whereas this guy only seemed to get half way up that moving van's ramp before goin' over the side, I got all the way to the top of it. However, the ramp was at such a steep angle to the van that once I got to the top my 1980 Yamaha XS1100 bottomed out right where the ramp met the van.
(...and let me tell ya, there's no worse feeling than throwin' your feet off the footpegs and findin' nothin' but air below 'em!!!)
