This might be the best trip I ever took. Three days in San Francisco. Mostly in the North Beach section where I stayed in a wonderful B&B. My pal Jamie Nelson (a native) showed me around the first day and I just drifted around after that. I had been to SF before but never got far from downtown or the tourist spots. This trip was mostly spent in the neighborhood.
I think I’ve finally learned how to travel (for me): No more than 3 days on the ground; two days for getting there and back; no flight longer than 3 hours.
