Therefore I was surprised to see in the FHWA article on the American recovery and reinvestment Act [see ASPIrE™ Fall 2009, p. 42] a background photograph of a person marking up a bridge technical design drawing using a fountain pen and a hand compass. While I still am partial to the beautiful nuance of using varying line weights on older, hand-drawn technical Editor's NotE Additional copies of ASPIrE may be purchased for a nominal price by writing to the Editor through "Contact Us" at the ASPIrE website, www.aspirebridge.org.

While the photograph accompanying the FHWA article was nostalgic, it doesn't at all represent the computer drafting and complex 4D modeling used by today's engineer, or ArrA projects. Roger Haight Parsons Brinckerhoff New York, NY [Editor's Reply] Roger… Thank you for the compliments. It is always encouraging to hear that we are achieving our goals to bring relevant technical information to bridge designers in an attractive and appreciated package. I have to admit that I too pondered the use of instruments from a bygone era shown in the background of this feature. I wondered if others would take notice. It appears that I am older than you! I used an ink compass, LeRoy lettering instruments, and a set of Koh-I-Noor Rapidograph ink pens to create what I think were very attractive standard drawings for the Wyoming Highway Department in 1965 and '66. The use of this background contrasts greatly with the exceptionally contemporary program we know as the ARRA. Maybe that's the irony. [roger Haight's response] Yes, it was good to hear you reminisce about the good old days—you are much older than I am!! ASPIRE_Winter10.indb 4 12/18/09 2:00:14 PM
