Absolutely not

The answer is: Within the park. Don't let the workers tell you it's near the fountain. It's not. You enter the park, turn left at the fountain and walk your legs off to get to the far corner - away from the Bizarro Ride and Superman Ride. It's a little beyond the Flume Ride. You get in line and wait for the open vehicle to drive you along. To make the ride seem more authentic they use vehicle without shock absorbers. I have heard older people say the bumping is murder on the back. I find it a little difficult and I'm only 70. It's a pleasant enough way to spend nearly half an hour sitting down. Animals are nice. Gone are the days of monkeys ripping your car apart or that one time a rhino totaled a Mercedes Benz. Everything is behind fences now. Enjoy
