Been wanting to play there for awhile now. My brother and I were actually going to meet up with you to play there last fall but the weather kept us from making the drive out. I've already played Deis Hill and Lincoln Park, so I'd like to make a day of Roscoe Ewing, Portage Lakes, and Arboretum Spiker.
Definitely worth checking out. Long, challenging but fair, good variety, and beautiful scenery.
Friends of Punderson DGC - most of the ratings are from when it was only 9 holes. With 18 holes it is in my top 5.
Two Mile Run Extension - 9 hole courses always get rated down. This is a par 35 coming in at 4,000 feet. There are some legit par 4s and 5s on this 9 hole course. If you play the reds and whites it makes for a great 18 holes.
I can second Punderson. It's pretty new, but like Portage Lakes it's a long, challenging wooded course well worth checking out.
In fact here's a video from each of those two courses. P Lakes longs, mix at Punderson.
