A group of five men are attempting to see a game in all 30 major leagues parks in just 27 days starting on June 16 with a Marlins-Mariners game at Safeco Field. They are hoping to raise money for the Jim Thorpe Little League in Hawthorne, CA.
They have three four days they plan to double up: June 21 (Dodgers in the afternoon, Padres at night), July 9 (Yankees by night day, Mets by night), July 10 (Phillies by day, Nationals by night), and July 11 (Cubs by day, Brewers by night)
The overnight trip they will have to take after the Padres game on June 21 to get to Denver for a day game at Coors Field will be tough, as the men are going to be driving the whole way. There is also a Kansas City-Detroit trip. And a Washington-Chicago trip.
The last park will be Milwaukee on July 11. And then they plan to stay in Milwaukee for two games.
