Can't sleep...

I woke up at 1:30 this morning, and was wide awake (vs. being absolutely groggy like I would normally be that early...).  Now it's almost 2:30, and I'm not feeling any closer to sleep...  Does this ever happen to you?  What do you do when you can't get back to sleep in the middle of the night?

Since I can't sleep, here are a few pictures. :)  This is Cole getting ready to go on a motorcycle ride with Grandpa Hollinger when we visited last month.  She sure had a blast! :)
