Thank-you. I have thought on our earlier posts, but a wedding 12000 miles away has slowed communication somewhat and some people with whom I am normally in contact are away this w/e. Yesterday for instance I went over three hundred km west into the bush with a young couple to keep the peace between a brother and sister older than 25yrs. (go figure¡). And back again is 600km of bad surface roads which can be rather tiring, with beasts and wild animals to avoid as well.
