You guessed it right. It is climbing these (and ones with more steps) 2x a day, carrying my Brompton on my right arm, with my T-bag on my left shoulder.
First when I started my multi-modal commutes, here in Atlanta, I used to take a sett on the bus. Now-a-days, I don't do that either. I simply stand by the exit door in the back of the bus. Somehow standing feels more comfortable these days, especially knowing that there is usually a day of sitting ahead, at least on the way into work.
My commuting continues, albeit at a slower pace than in Irving.
