cliffs anything and everything! people who work for him (he has a small outdoor adventure guide business) and anyone he's taken on said adventures. he's also a ski instructor so that one person he tried to teach but just couldn't get it. any number of ex-girlfriends as he's a serial monogamist, a recentish ex fiancee, and a female a little younger for something specific. also maybe someone who rents a room in his house? and anything else!
