This sounds like it could be fun! The National Pony Express, Nevada Division, will be holding a celebration in June to mark the 146th anniversary of the Pony Express. Call 775-374-0596 or email ponyexpress<at>mail.com.
There's also a Pony Express Museum in Missouri, and more information available at the Virtual Museum of the City of San Francisco.
