Dear mr. sir lowteck,

This one was interesting.
Almost two thousand marbles rolling down Lombard street, San Francisco's famous windy road. Prank monkey wishes prank monkey had a good sound recorder. It came out good enough in the videos. Also we had to do this one at night. The sound was absolutely amazing. It was as if Jesus himself wielded an oversized novelty rainstick. All the noise you hear in the videos was from the marbles. Prank monkey was holding the camera a few curves down from the top and got pelted by many oncoming marbles, as you can see in the footage.

Sincerely,
Prank Monkey
