There are plenty of trees. I've not been to Eugene to compare, though only to Seattle in the PNW. It's not as green as Olympic Natl Park here, but the Smokies would give Olympic a run for the money. It's definitely greener than most parts of Cali that I have seen (lived in LA for a year, traveled up and down). Raleigh, which is not as green as CH/Carrboro, has the nickname of "The City of Oaks" if that helps.
CH/Carrboro and the triangle in general are in the piedmont of NC. The piedmont is a geographical/topographical(?) designation that runs through the middle of NC, SC, VA, maybe GA. It was named after the piedmont section of Italy I believe. It is characterized by gently rolling hills. I was born in the coastal plain area of NC (ancient ocean bed) and it is much sandier and flatter and lots of scraggly pine trees grow there. The soil around CH/Carrboro is pretty clayey and the forests tend to be a good mix of deciduous tree (oaks, poplar, sweetgum, etc) and pines. (NC is the "pine tree state" and "land of the long leaf pine".)
I would say this area of the state and probably NC in general is a gentler homier green than the PNW which I woud characterize as maybe more rugged, although certainly there are rugged places in the mts.
do a google image search on "Eno River" or "piedmont NC" for pictures.
No topless, though. definitely plenty of NIP, but no topless. I think Asheville might have more hippies, but the CH/Carrboro/Durham area has a lot of crunchy folks though they don't all embrace the hippie label. We do have plenty that do, though. Great food. Fantastic organic farm scene. Carrboro farmer's mkt is da bomb.http://www.bolincreek.org/photos.shtml

(one guy's take on towns in NC. I like his perspective. He's got photos, too, if you nose around a bit. It's a few years out of date — maybe 5 — but pretty much on the money.)
