I don't live in Portland but while i was visiting i went to the omsi and GOD WHAT A COOL EXPERIENCE. Its a big natural history museum, and i believe they have a big lego Jurassic park exhibit out rn if you can make that ^_^!! Aside from that they have a bunch of cool exhibits there, ofc their fossils on display are incredible but also they have some great astronomy and even a submarine tour i believe
