....well, let's see. about 300 feet from the east end of 21 at samo,
there are two gas stations, one of which is probably where they took
the measurements. go about 2000 feet northeast of the runway, and you
have interstate 10, which starts to bottle up most days right around
samo because it ends and/or becomes the PCH in a couple miles; go one
mile straight down the approach path to the runway, and you have one
of the more notorious highway interchanges in california: the 10/405,
where it is not uncommon for cars (and large trucks) to sit idling for
a good bit more than 30 minutes, after having navigated the sepulveda
pass from the getty on down to the interchange itself at about 3 mph.
oh, and by the way: when you're holding for departure at samo, your
exhaust is pointed AWAY from the houses and apartments.

The prevailing wind is from the WEST so all the exhaust crosses BUNDY
and heads into the houses.

bundy drive, ocean park blvd. and national blvd, all of which are
heavily travelled day and night. think any of those might contribute
to local pollution?

Typical of GA shills to change the subject or attack the sources.
