Bowling + No Nap= a questionable time

Zack is really in that in between stage where he doesn't always take a nap because he isn't tired but by 6 or 7pm he is a bear. This past week Cliffy came home and wanted to go "real bowling" (as opposed to Wii bowling) so we loaded up hit Sunset Station to bowl. I opted to watch them and about half way through their first game Zack was having a hard time keeping his body off the ground. He was too tired to bowl. It was also a little scary because they put another family next to us and Zack would run and bowl and about the time he should throw the ball he would watch the kid next to him. YIKES good thing no one got hurt. So no nap plus evening bowling not so sure that's a good idea.
