I currently commute from Alexandria VA to downtown DC, near the capitol. It's a fabulous commute, mostly on paths or quiet streets. I love it. It's a big quality of life factor for me. But the job ain't so great (not horrible, but just not great). I'm considering a much more interesting job in Silver Spring, right next to the Silver Spring metro. But I am doubtful that I can commute the whole way -- it's just too long -- I'm kind of a slow biker. It takes me 40 min. to go 7.5 miles. Anyone do this commute? Or anyone do part of it, and then take a bus or the metro for part of it? I really can't spend more than an hour commuting door-to-door each way (two little kids at home eager to see me each night).

Thanks for any suggestions!
