Musings
- Feeding leftover shrimp and scallops to the seagulls was kind of fun.
- Maybe trying to drink up the remaining beer from the cooler the night before we started the drive home wasn’t the best idea ever, but it was kind of fun.
- Driving through rural Alabama listening to Monster Hunter International is pretty cool in a very geeky way.
- Making a pit stop to buy a half bushel of fresh peaches and eat some warm-from-the-oven peach cobbler was the highlight of the day.
- If the people who made and served our lunch were moving any slower, they would have caused the time stream to run backwards to a time when the vein in my forehead wasn’t pulsing.
- It’s disheartening to realize that the price of gas at the tourist trap in Florida is 75 cents a gallon less than it is at home.
- How to know you’re done driving for the day – You check into the hotel, order pizza, let the kids go down to the pool, and let them veg in front of the Disney Channel while they eat and you try to get feeling back in your legs.
