Must do in Portland?

Hi!

I am from nw WA and have nevere been to Portland, somehow.

We have a wedding in Depoe Bay this Thursday, and plan to stay in Lincoln City through Tuesday.

We are going to visit Portland on Saturday. Apparently there is a car show the teens want to go to.

We will have 4 teen boys with us (16/17).

Any suggestions of things to see or do?

Just for the adults or things the teens might like.

They want to go thrifting for clothes, as well. Best places for that?

We could always visit Portland a second day, if needed or the teens want.

Suggestions for things to do between Lincoln City and Newport are welcome as well!

Thanks so much!
