A scientist recently had a great idea - affix a CO2 sensor on top of the Space Needle to monitor daily fluctuations of the now-famous greenhouse gas around downtown Seattle. Then, display the information in real time so any random Joe can see how the measurements go up and down
(http://www.pmel.noaa.gov/co2/story/Space+Needle) due to wind, weather, morning/evening commutes, etc. Science - love it!
Adrienne's boss was that scientist with the idea - so she got the opportunity to go up the Space Needle in 70 degree weather to do a little maintenance on the instruments. She literally went to the tip-top of the Needle - above the restaurant, above the observation deck, through the boiler room, up 4-stories of telephone-pole ladders, and out to the scene you see above and below.
Nice job perk!
