The Emerald Isle is calling. Ten San Jose officials will fly this week to Dublin, Ireland, for the bi-annual “Sister City” trip, which is basically a pub crawl disguised as a city-sponsored economic development junket. Among the lucky 10 are four councilmembers (Xavier Campos, Rose Herrera, Ash Kalra and Johnny Khamis); three department heads (budget director Jennifer Maguire; Joe Hedges, of economic development; and environmental services’ Kerrie Romanow); two council chiefs of staff (Shane Patrick Connolly, for Khamis; and Mary Anne Groen, for Herrera); and one soon-to-retire city manager, Debra Figone. If that seems like overkill, well, it is.
