Several years ago I took, "Basic Arborist" training so that I could have more skills to use for the Volunteer work I do.
At that time I was thinking of the trail building and maintenance I did with the American Hiking Society. The AHS has week long projects that give volunteers the opportunity to perform services at state and national parks. I was thrilled to find out there is a national park in the Virgin Islands. It's not so thrilling to be rebuilding trails in 90 degree heat and %80 humidity. It was the week at Wildcat Mountain in Wisconsin though that made me want to sharpen up my chainsaw safety skills and the only class I could find in the area that awarded certifications also required you to climb the trees you were pruning. The experience was, in technical terms, "totally awesome".
