In April of this year I had the pleasure of backpacking along a 80-mile trail in Scotland, the Rob Roy Way . Situated in the Highlands near Glasgow, the trail begins near Loch Lomond and winds its way to the town of Pitlochry on the edge of the famous Cairngorms National Park in central Scotland. My partner and two other long-time friends and hiking buddies spread the 80 miles over 8 days. Three highlights of the trip: the lovely Highland scenery; the weather was delightful for hiking - cool-ish and dry; and there were no major injuries along the trail.

Before the trip, my naive idea of the Highlands was of windswept moors, heather, and stones. But, the reality of what I saw in this corner of Scotland was much more managed, wit...

They also appear to be dead, with a desiccated brownish color. But as the plant grows taller, up to 60 feet, it completely changes its form of its leaves, and the trunk grows multiple branches forming a lollipop shaped canopy. The tender green leaves of the mature tree appear similar to eucalyptus leaves, with smooth edges. These tender mature leaves are well above the reach of grazing animals like the giant 12-ft moa bird that roamed New Zealand...
