The preferred weekend for OTOL Philadelphia Area RailFest 2005 would be Saturday & Sunday, March 19th and 20th. Palm Sunday falls over this weekend, as does the first day of spring, and the return of the swallows to San Juan Capistrano. Would any of this pose a problem for you attending the fest? Remember you don't have to participate on both days, and you can feel free to either leave early or join the fest in progress.
