We finished an early dinner in Concrete, Washington (yes, it's named after the building material), on the west side of the Cascades and really wanted to continue on. The upside was less traffic in the early evening and the potential for a fabulous sunset in the mountains, and we weren't ready to call it a day anyway. The downside of pushing ahead meant more than 100 miles of road with no services, including cell-phone coverage, as darkness fell. The greatest danger, however, was the risk of encountering deer. Known to come out at dusk, deer are credited with killing more motorists than any other creature in the U.S.; we would be heading into deer country at the worst possible time. So with caution thrown to the wind, we called ahead, secured a motel for the night on the other side of the mountains, gassed up and took off.
