a picture of an Australian road sign for the town of "Colinton" which MacLane said was named after Linton's antipodal dual. Foreign (i.e., non-North-American) category theorists were represented by (at least) Eduardo Dubuc and Sabah Fakir.
Presumably I was considered North American at the time as the Bowdoin Seminar came between a postdoc at U Illinois (Champ-Urb) and a assistant professorship at Tulane. Sammy commented that I began the summer as an Australian and ended up an all American boy. Sammy was prone to exaggeration. I have wonderful memories of that summer: Mac Lane's incredible lectures (every morning -- 2 hours I think -- for the whole summer), freezing water at the beach although the weather was hot, the "pro-seminars" run by new postdocs that were organized after Mac Lane's first lecture, becoming marooned when the tide came in and Eduardo Dubuc (up to his chest in water) carried Joan Machez (sp?) while I supported her broken leg in its cast, the tall dormitory with 16 bedrooms per level and Sammy at the top in the penthouse, that clam and lobster bake, buying beer at the supermarket where the under-aged checkout girl had to get an older person to punch in the price of the beer! and many other things mathematical and non. Mac Lane, Dubuc, Duskin and I moved down to Tulane after that for its "Year on Category Theory 1969-70". --Ross
