Furthest reception from your tuner and how?


I am moving to a remote location - about 4 hours from San Francisco and 6 hours from Portland. There is some radio, but... I'm curious. A few questions for you tuner guru guys:

What equipment do you use?
Modded or stock?
How many filter and gangs, antennas, sleuths, etc.?
What's the most remote signal you have been able to pull?
How has it sounded?
Any thoughts on things you would try if given the opportunity?
biomimetic
If by 4-6 hours you mean 200-300 miles then it will be impossible to pick up FM stations from that distance. FM is basically line of sight and at 200 miles you are well beyond the horizon.
Hmmm... sounds like maybe people were pushing the truth a bit when they were saying they were in Eugene and picking up Portland and Seattle stations?
A hi gain antenna is the answer if you`re in the boonies. If the stations are scattered, add a rotor.
I know it's all relative, but I'm looking for someone to answer my question about earth coverage distances and gain sensitivity. Does anyone know the formula for FM/Earth coverage based on parallax, and antenna height? Or where I might find it? In terms of absolute distances?
