About nine years ago, before moving to CA I leased a mountaintop site 
near Sacramento, and had a 100W rig feeding a loaded dipole sloping away 
from a 170 ft tower.  I worked a guy in the Caribbean from there at 
least an hour before my sunset.

Working contests on Topband from my home 70 miles S of San Francisco 
with 1.5kW, an omni vertical, and Beverages, I regularly hear east coast 
stations at least two hours before my sunset, but they can rarely hear 
me, primarily because they're listening on Beverages aimed to EU. I can 
also regularly work anyone I can hear out to about 1,000 miles in this 
time frame -- Seattle, Phoenix, CO, NM.  After my sunrise, what I hear 
from the west varies a lot from day to day, but I've made a good number 
of 4,500-5,500 mile Qs a half hour after sunrise.
