Of course in Costa Rica there will never be a problem having to drive up such a steep driveway in the snow or ice. There is a maintenance issue to make sure that there is no erosion on the uphill slope. I guess that is a small price to pay for the benefit of a view.
If you have not done so already, I respectfully recommend that you check out the photos of Varenna, Italy that we have posted on our Viva la Voyage travel photo site. Varenna is located on the eastern shore of Lake Como, an Alpine lake north of Milan. I think Lake Como is one of the most beautiful spots on earth.
