My sister Melanie came to visit us for a week at the end of March and it was action-packed.
First, we took a Segway tour of Dallas. Riding a Segway is different than you think. There's no motor, so you're not just standing on a still platform until you push some button to move. Instead, it runs on a gyroscope, so it will move whenever you are on it. Like a skateboard. So you have to find your balance, and then control its movements (and non-movements) with your body. Once you get the hang of it, it's quite fun. And easy, like riding a bike -- hard to learn, easy to do once you know how. (and unlike riding a bike, no painful falls in the training process!)
It was a gorgeous day. We did this tour for a couple hours, cruising around the downtown area, then toured the Sixth Floor Museum at Dealey Plaza, where JFK was assassinated.
Two Segway pros:

Melanie stands on the "X" that marks the spot of the assassination (and nearly got assassinated by a bus herself when I took too long to get the shot), with the Schoolbook Depository and the sniper window in the background (far right, second down from the top -- the square one on the end of the row of arched windows).

Later in the weekend (after subjecting Melanie to an especially windy and lackluster soccer game by my little Skyhawks), we visited the Fort Worth Zoo and were treated to a (thankfully) rare sight: mating lions. When we first approached the lion area, I was surprised to see a female in the male's area; usually the male is on one side and the females are on the other, with a wall separating them completely. But it didn't take long for us to see why they were together: it's mating season! We saw the full, and very short, performance. Melanie thinks she saw a nature program that explained they do this over and over in short spurts. Anyway, here is our king of the jungle celebrating his efforts with a big ROAR! Actually, hearing a lion roar that closely was really cool.

And then on to more gentle creatures:

And then back to the less-gentle variety. This thing was fearsome looking, just hanging there so close. It looks prehistoric.
