Where Can I Find Frequencies?

I was lucky enough to be given a hand held multi-band radio a couple days ago and finally got around to making use of it tonight. Picks up on the Weather, Police, Air, CB, TV1, and FM.
I tuned into the Air band to see if I could pick anything up. So far I've only found one frequency range that seems to have anything. I've heard a couple of flights loud and clear while most are pretty distorted with static. One was still over Ohio, American 363 from New York to Chicago was the last one I could hear clearly.
So I'm curious, where might I find a list of frequencies in the area so I know an area to tune into them a little easier. Its not a digital readout so I have to play with a range till somebody talks. Right now I'm somewhere between 125MHz and 136MHz. Closer to 136. Kind of interesting to listen in, especially if I get the chance during the day when the sky above is really busy. Right now half the problem is severe storms that are approaching causing a lot of static while tuning in anything from the west.
