I was at a PC rental terminal in the Kinkos in Harvard Square a few nights ago and there were some college age people speaking in Spanish. When I took a look at what they were doing they had a green card and were making copies in which the pictures were being switched. I though hey I know is going to be interested the Alipac readers. I suppose that I could have phoned the group in but I do not know if the Cambridge Police would have cared. I also got the impression that the students were trying to get into bars not work with them.
