Is anyone going to the ASCE "Applications of Advanced Technology" conference in Chicago this August? I might be able to get you a moderatorship which looks like a slight break on the registration fee. Let me know ASAP if interested. http://www.asce.org/conferences/AATT06/ -- Ed Christopher 708-283-3534 (V) 708-574-8131 (cell) FHWA RC-TST-PLN 19900 Governors Dr Olympia Fields, IL 60461
