I'll always be that person.
But now I tend to chase after challenges instead of fire trucks. I bike a bit faster; hike a bit farther; there's a lot to see, and I don't get to stay 3 forever.
Overestimating. There's always left overs, and I always bring my headlamp.
Friends (I am a pack animal after all)
Even more awesome: If you have an epic adventure you're interested in trying, I'm always willing to be a partner in crime.
