I've only been to three Nationals.
2002 in Chicago.
2004 in Cleveland.
2023 in Chicago.
In my younger days (prior to 2002) I really didn't have the money to hit these big shows and would stick to the regional St. Louis shows because i could make a day trip out of it and not have to spend money on flights or hotels. Now that money isn't an issue it seems work or family obligations typically get in the way as it did again this year. Hopefully next year I'll make it back to Chicago.
