Did you know alligators can climb trees? Or that they can hear your pinky hit the water four miles away? Or that the blazing color of bougainvillea comes not from its flowers but from its leaves? These fun facts and more can be had for a buck and 30 minutes of your time at Knollwood Groves in Boynton Beach. Originally owned by the vaudeville comedy team Freeman Gosden and Charles Correll, better known as Amos and Andy, the 71-year-old orange grove offers visitors a slice of Old Florida and enough trivia to win bar bets for years to come. A tractor-pulled cart leaves every hour on the hour for tours of the pesticide-free grove, traveling through a genuine Florida jungle hammock, past a 1000-year-old water oak and a four-story-high bougainvillea vine, as well as gumbo limbo, ginger, and coffee trees. For the kiddies it makes stops to visit turtles, a wild boar, and of course gators. On Saturdays at 2 p.m. the grove also features an alligator show with Martin Twofeather. At $6 for adults and $4 for kids, it ain't half bad -- you can even pet the gator. Still the $1 tram tour, which begins at 10 a.m. and ends at 4 p.m., is better. The grove is open from 8:30 a.m. to 5:30 p.m. seven days a week in season. (It's closed Sundays in the summer.) There's even a gift shop that sells funky Florida stuff, like plastic gators that sing, and a fruit stand where you can pick up oranges, green pepper or papaya jelly, and vine-ripe tomatoes for, you guessed it, a buck a pound.
