From my memory, in regards to her liking country music, she's been a Dolly Parton fan for a while. She played it while getting ready for her birthday during the Joe Era. Plus at one point she mentions reading a magazine because Dolly Parton was being interviewed.
As far as hiking, she's recorded one hike with Chris and a handful with Joe, and I guess she mentioned going in HK. She may not be Joe level outdoorsy, but it does seem to be a fairly consistent pastime in her recorded history. She's just a very prissy hiker who mainly goes with a partner, like her travels.
Maybe now that she's older, she's leaning into it more.
Her main efforts at transforming herself for a man was becoming more boujie for Chris, a sad attempt at quirky humor for Joe, and being frugal for Rick.
