Re: OT: giant pipes down Portola Avenue in Santa Cruz andother natural reverbs

I was just skateboarding at lunch... we've been bombing hills out in the 
Santa Cruz mountains. Anyway, we dropped down this fast pitch of a 
divided, 2 level street, where one direction is about 10 feet higher than 
the opposite direction. The lower path wall being reinforced with the 
corrugated siding, separated by something like 6" x 6" wood posts. The 
first time we passed it my partner said he thought he had a wheel coming 
loose or something. The next time around, I listened for it, and it was 
the sound of my wheels on the asphalt reflected back, doppler effect and 
all. We probably go past that wall at about 25 mph, maybe 3-5 feet away 
from it.

If you play something really loud (further back is better) at
the broad side of a building covered with vertical corrugated
siding, and then dance wildly back and forth between the
building and the sound source, you get the equivalent of a
physical comb filter/phaser.  If you can find two buildings like
this parallel to each other, it hurts.
