I work as a SR Purchasing Engineer in an Aerospace business. We make fluid power distribution systems and hydraulic pumps and motorpumps for the defense and aerospace market. Our business has a "unit" on every major airframe that has been in the sky since the early 50s. I generally work from 8-5, but have been known to work a little more, a little less. I am lucky to live in an area that I can go ride my bike from my front door. I have a good 10 mile, 16 mile, 21 mile, and 32 mile loop right from my house. Also, I have a pool at the country club that is about 1/2 from my house (still in the neighborhood). Running isn't an issue around here, and I can run whenever/wherever I see fit.
