I love the sound of frogs at night. Especially the bullfrogs. I have a pond also but it's not near the house, so I don't get there often at night lately.
There are lots of frogs where I live in this rural area. I come down the 1/2 mile right-of-way on a summer night though the wooded/swampy parts, roll down my windows, and their sound is deafening. It's the sign of a healthy ecology. When I was a kid, we had frogs in a small goldfish pond. They are amazing critters, making as astounding a metamorphosis as caterpillars into butterflies.
