Ozone

[Jim Holland]

Greetings!

	Well, Mr. Deuterium (D2) - apropos since we are talking about "O3" -
The PRCo tunnel had been around ca.-50-years when I was riding thru it,
and service thru the tunnel during that 50-years had been intense with
9-regular routes working the tunnel 7-days a week and a few others for
rush hours only.  How long and how many routes run thru the SEATAC
tunnel?
