If you're a parent, and you're into awesome, completely free activities, I'd like to put forward a recommendation for fire station open houses. This is the second one we've been to in our area. All of the vehicles are available for inspection, the firefighters are available for questioning, Smokey the Bear was on hand for high fives, there was a completely free and also delicious lunch, prepared by the firefighters themselves, a rescue helicopter was flown in with associated personnel, and they had a climbing wall.
Did I mention the part where it was free?
And they feed you?
My sometimes overly cautious four-year-old blew my mind by kicking major ass on the climbing wall, by the way.
