It does take a sense of humor to deal with angry bike shop guys, but I am always polite and eventually get them to talk to me. He said that no, it couldn't be adjusted so I got down on the floor and took a look at it, and I could only have gotten another half inch or so adjusting it. Currently I am leaning towards a Tern I saw at an REI which would probably work with some of the adaptations from ThorUSA. The REI guy was friendly, didn't know anything about folders and tried to steer me to a regular bike. You really have to laugh sometimes.
