Countdown to Glacier Park!

In 4.5 days Jon and I leave for Glacier Park, Montana. It's hard to believe, but it's actually our first vacation where we're not either visiting family or attending a wedding or funeral since our honeymoon over 4 years ago! Crazy right? We're leaving here Saturday morning and will arrive at Glacier Park Sunday afternoon. We're staying there Sunday, Monday, and Tuesday nights, and then will drive back Wednesday/Thursday. So far all I have planned/booked is a horse-back riding tour. Anyone who's been there, any suggestions are appreciated!
