Between May 15 and 17, the national AIA Convention and Exhibition comes to Boston for the first time in 15 years. The BSA has designed 85 tours showcasing great design throughout Boston and New England. We now are seeking guides for walking tours of Boston City Hall, the Institute of Contemporary Art, the Seaport District and Harvard Square as well as for boat tours on the Charles and Boston Harbor. The BSA supplies the script, tour group and transportation. You provide your love for Boston and enthusiasm for its architecture. To volunteer or learn more, email Beatrice Nessen at bnessen@architects.org. To register or learn more about the convention, visit www.architects.org/2008.
