Susan Murphy: Sue is a retired banking executive spending her working life in San Diego and New York City. Having spent 30 years in the concrete jungle of NYC, Sue and her husband Ron, longed to retire to a place out west that would provide the outdoor opportunities they missed. Santa Fe won out over all other locations for its diverse community, spectacular open lands and scenery; they moved here 10 years ago. Activities include hiking, mushrooming, horseback riding, skiing and golf.
Her appreciation for our natural environments and open spaces grew from being raised in a family immersed in the Boy Scouts of America which meant that Sue spent many summer weeks at Camp with family including Piedmont in New Mexico. Living in New York City provided a stark contrast for someone that grew up in Southern California in the 1950s and 60s.
Sue participates in trail work days at Galisteo Basin. She also organizes single day and multi-day horseback trips for groups including spouses that ride only occasionally, and organized mushroom hikes led by Mycologist Art Judd, who recently passed. Eight years ago, she initiated the Bluebird Trail in Las Campanas installing birdhouses throughout the community to support bird nesting while raising money that is donated to local not-for-profits. This program continues to grow each year. Sue is a member of the Santa Fe County Horse Coalition and the Northern New Mexico Horsemen’s Association.
