I traveled to SF for my first significant work. I did 5 1/2 hours one day and 4 more the next. My artist was guesting at the opening of Analog in the tenderloin district. We were in a loft overlooking the street. Observing street life of the Tenderloin kept me entertained for 90% of the time. Drug deals,hookers, homeless, insane. Even two women beating up some guy. IDK if it was me reaching the end of my rope but the last hour of each day was pretty tough. Seemed like my guy just had to edge into the armpit area from the front one day and from the backside the next. Both times right at the end of the session. I was pretty tense. All I could do then was tell myself "get through to the next time he goes to the ink".
