No? That's how my first field trip was in the country with the school (several years ago...) The children had so much fun, I decided to take some kids to hang out in the capital. These children are ones I've had long relationships with, some I taught to read, some have been to my house for pancake parties, one set of parents offered my parents a goat the next time they return, and all are from very poor families. Most had never been to the capital.
First, we crammed into the bus on the way to the capital. Then we got to use the metro, which was very exciting. Of course, the kids had to use the restroom, but we got special permission to use the private metro bathrooms (I think the guards felt sorry for me). Let me describe the experience of helping 5 children use an escalator for the first time: Alicia, kid in hand, gets on escalator going down. Alicia then runs up stairs to collect next child, who is also afraid of mounting escalator. Rinse and repeat until all children are clutching the side of the downward moving monster, huge grins on their faces.
The metro was a hit, and we hadn't even gotten to the fun part. I felt like giving someone a present and they're more interested in the wrapping paper than in the gift. We tried to go to the cinema, but they don't open until nighttime here, so instead we went to a park that overlooked the seashore.
We enjoyed looking at the crabs scuttling around the rocks, and I think they liked their first view of the ocean, but, if anyone knows kids, they know that they eat and drink and pee like crazy, so we had to introduce the food element. So we went to McDonalds! The kids got happy meals, and we played with the cardboard milk mustache cutouts they came with. Some highlights of this phase: Kids learned about automatic hand dryers, soap dispensers, and that "chicken nuggets" look nothing like the chicken they are used to eating (which is freshly killed, cooked, and on the bone).
After eating and playing with Happy Meal toys, an employee called us a cab. The driver was kind enough to joke with the kids, drive us past a huge Christmas tree, and take us to the zoo. Memorable hightlight: Enrique learning how to operate door handle of car. While the car was moving. Like I said, we had a really nice driver.
The zoo was fun, we saw hippos and primates and birds and reptiles and played on see-saws and slides and drank, ate, and went to the bathroom. Another taxi (not so nice this time, but we were experts at the sitting and not opening doors part) took us to an ice cream store!
The ice cream was a nice touch, as kids apparently wither up and float away if they are not fed every hour. I gained a lot of respect for the patience of my parents this trip. The kids picked out thier own flavors, and the employee was nice enough to help them say please and thank you (and let us use the employee bathroom). As we were leaving, he took a picture of us, and asked if I was a Peace Corps volunteer. When I asked him how he knew, he said "it's stamped on your forehead."

Finally, how do you know if your trip has been a success? When the kids are sleeping on the bus ride home. So cute when they're sleeping, and not asking to be fed, watered, or taken to the restroom...
I'm leaving the country in 10 days, hopefully, but this one particular day of around 1,000 days here was one of the best.
