Jim Erwin - Vice Chair

My most enjoyable contribution to Sierra Club has been leading ICO (Inspiring Connections Outdoors) trips in North Carolina. My most memorable Sierra trip was a service trip in the Superstition Wilderness. We were carrying big rocks and spiny cactus, days on end, to make a badly abused horse campsite unusable. The woman who brought tweezers was voted best-liked trip member! Trudging out, after a while, my new friend said “That was terrible.” I said “Yep.” After a while he said, “After two weeks, wish I was back here again.” I said “Yep.” Two weeks later he emailed me: “Wish I was back there again.” I wrote him back, “Me too.”

I have taken the Sierra ten-day leadership training backpacking trip but sadly have not found the time to follow through on that. I enjoy helping out the local Tarflower Chapter of the Florida Native Plant society. My favorite job was my first, teaching college composition. My B.A. is from University of Pennsylvania, M.A. from UNC Chapel Hill, both in English. I retired six years ago from 30 years of database administration work – how else can you make a living with a degree in English?
