Ha I dunno, I had a damn good time with my friend when I went up for my spring break.
Their floor of dorms had no RA, everyone in the hall was chill and all the doors were kept open. Kids just walking between rooms kicking it and drinking large amounts of beer and downing shots of jager. You live walking distance from all your homies. On top of that his brother had a house about a mile away so party or vape sesh every night and it was never too far to walk back if we got too shitty.
One thing that does get on my nerves about Oregon though, liquor can only be sold in liquor stores that close at like 8. They make up for it though by carrying some of the best beer in the country, even at the supermarkets.
If you're in Eugene, check out the Steelhead brewery. I got a gallon of hoppasaurus rex for $8, a good quality IPA with 10% alc, gets you really drunk but not in the bad keystone light headache sort of way.
