Pros:
Benson, which has seen encroachment improvements the last few years, is a pitch 'n' putt with noisy-but-nice winter views. This is another one of those good beginner courses that experienced players are likely to use only if they stop to stretch and pee---or if their self-worth has been wrecked lately by Blue Lake, Milo, etc. Makes for decent long-putt practice or ace shots. You might use a roller or skip on # 1. If the creek is up when you throw over #2 your disc could wash downstream if you boner your drive. Plenty of mature trees as obstacles, so shady and cool on a hot summer-driving day. In fact, when its leafed out, you lose the gorge views and almost wish for some breaks in the cover. Nicely mowed, and only a bit of rugged vegetation behind baskets 1, 3 and 5. Also a good place to stop for a lunch break, or some light fishing at the small adjoining lake. And Multnomah Falls is 3/4 mile away, so theoretically you could have the family drop you off, play 2 rounds and then walk the train tracks down to the falls...
Cons:
$5 fee or state park yearly pass, but its rarely crowded and only takes 20 min. to poach. I-84 is 50 yds away and always noisy. Major summer holiday-goers will render the course unplayable.
Other Thoughts:
As above, its OK if you needed to stop for a driving break anyways. Not really a discing destination: better to stop at Rooster Rock or Locks Approach, unless you've got newbs/children who want to have a successful round.
