"naturally wooded" does not bode well for WiFi. Trees are much better 
than walls at absorbing 2.4GHz signals due to their high water content. 
Mountains block 2.4GHz even better. If the woods are deciduous, it may 
work well in the winter but fade away come spring.

If the road is fairly straight, a directional antenna like a Yagi at one 
end might give you coverage there. As for the rest of your property, you 
will have to get an omni antenna up high, say one of your mountains.

You may be better off with something that uses lower frequencies. The 
old analogue cordless phones have much better range than 2.4GHz digital
