There are many places and opportunities to celebrate May Day (the worker holiday that most people in the world celebrate instead of the US's Labor Day) this year and GB's Slowdown calendar will keep you in the loop! On Friday you can get some history lessons with the folk's organizing a free conference on anarchism and a film festival at Loyola, the conference continues through the weekend but the downtown walking tour starts friday at 330. Then on May 1st you can join up with the immigrant rights demonstration that promises to be huge (especially after last night's raid's in Little Village) and on May 2 there is another walking tour and celebration at the Hull House.
