I can't find any gymnastics class or club in Portland OR... is anyone have any idea with where they are?

Answer 1

I don't have time to Google it for you, but I used to live just north of Portland in Vancouver, Washington and am aware of several places which you might want to check out.
Try looking up the Oregon Gymnastics Academy, the Oregon Sports Authority, and The Children's Gym. That is just a start, I'm sure, but this is off the top of my head and I only remember those because a friend of mine was looking up the same stuff for her son. Good luck finding something. I hope that gives you a start! :-)
