What is fun to do in Eugene oregon that is not boring or expensive?|165484

We are from nevada and up visiting family in oregon. We can_t figure out what to do... any suggestions?

Saturday market (downtown)
Alton Baker park (picnic just hang out)
Prince Pucklers Ice cream - awesome
Water skiing at Fern Ridge
Take in an event at U of O (Ducks)
Fishing on the McKenzie River

If you_re from Vegas or Reno, you may consider those things boring but that_s life in OR.
