I recently received the following information from the Washington Nationals about peanut free accommodations:
"This will be our 6th season having peanut free suites for games. We had one at our old stadium and this will be the fifth here at Nationals Park. Dates are as follows:
Saturday May 19th vs. Baltimore; 7:15PM
Saturday May 19th vs. Baltimore; 7:15PM
Sunday, July 22nd vs. Atlanta, 1:35PM
Saturday, August 18th vs. New York Mets, 7:05PM
Sunday, September 9th vs. Miami; 1:35PM
All of the tickets are in our party suites in left field and cost $25 per ticket."
