In 1994, when I first started commuting into Bethesda, from the north (Columbia), I could leave at 6:30am and be in the gym by 7. If I had to go in late, leaving anytime after maybe 9:15am meant a quick ride around the beltway.
By 2004, when I retired (!!!), getting into Bethesda by 7 meant leaving by 5:45am. I ditched the 7am routine. That's nuts. Leaving the house at 8, I resorted to back roads, obscure back roads, more obscure with every 4br house and townhouse that got built, and usually got in in about 1:20/1:30. Getting in late? Gridlock on the Beltway until maybe 10:45, which resolved until 11:40, and then it was pretty constant until 7:30pm.
Snow or rain?? It was a good thing they didn't stock razor blades in our restrooms at work. I wouldn't be here.
Then, you have to deal with all the "inside the beltway" bs. It's very stressed out, that area.
Never again. Never again.
