The first ever 'Stros Under The Stars event let Astros fans young and old spend an entire night at the ballpark. People could play catch in the outfield, take a tour of the clubhouse and got to sleep in right field.
Fans say sleeping on the grass was really comfortable and you wouldn't realize how soft it is.
"This was amazing. It was actually more than I expected. We got to throw in the outfield. I mean just be on the field all night, it was absolutely incredible," said one fan.
Before leaving Sunday morning, there was time set aside for guests to run the bases like their favorite Astros players.
