Summer already approaching?

My final days are coming up where I have the opportunity to really kick ass as a mom: Summer.
I read all kinds of blogs about mothers who come up with all these fun activities and crafts to do with their kids. My kids don't like crafts but they love to go places and do different things. Last summer we kept pretty busy with friends and playdates and the pool, and it went by quickly. This year I think I want to challenge myself. Really challenge myself to do great things with them before they start Kindergarten and we don't have long stretches of hours to fill with activities anymore. Before I know it they'll be gone all day and when they come home we'll have homework, then dinner, then bed! I want to make this summer meaningful and memorable. I'm determined to. I'm well aware how difficult this will be for me, but I feel like it would be a great accomplishment and something special that I can do for my boys since we won't be together as much anymore come Fall. Everyday we will do something GREAT! This will be my Summer Challenge.
