How far away does a 3 hour drive from DCA get you? My limit on driving to work has always been 4-5 hours. That's about how long it takes to go to the airport, park, wait to board, fly to base, get bags, etc.. But at least I knew my car wouldn't leave without me on the last day. I'm just curious as far as traffic and what not. The option to drive to work makes this a whole different job.
