I've had QSOs from my home in California with hams in Hawaii, Japan, Australia, England, and Poland, among others. It depends on a number of things, like the band you're on, the time of day, antenna, power, mode, etc.. I don't have a big antenna farm or 2KW linear amps, just 100 W radio over wire antennas. In fact, I've made long distance contacts in QRP mode, just 10W or less. It's a lot like fishing. You keep throwing your lure into the water until something takes it.
