As you may recall from my 365 project (and later posts), I sometimes struggle a bit with social anxiety bordering on agoraphobia.
It has lessened a good deal in recent years: I think it has something to do with being married and thus being around people more or less most of the time. But I felt it some the first couple of days in Costa Rica. I got over it a bit as the trip wore on, but the first few days saw me going from the hotel to Zona Franca Metropolitana where Equifax has one of its Costa Rican offices.
In addition to the iPhone, I also took the D7000 with the Nikkor 28-105 f/3.5-4.5 D (and the Nikon 50mm f/1.8 E Series, which never got used) and the LC-A and a couple of rolls of film.
The picture above is from the D7000/Nikkor 28-105 combo; the one below is from the LC-A and Agfa Vista Plus 200 film.
