Ron,
There are a lot of spot on comments above. I played three Trail locations about 10 years ago, when I was younger and a bit better player. I generally enjoyed the courses, though they are repetitive and a slog in places. It was a great guys trip, and I loved the barbecue places we found (except on a Sunday, when everything was closed). The courses we played were Capitol Hill Senator and Legislator, Cambrian Ridge three nines, and Grand National Lake and Links. Of these, Capitol Hill Senator and Grand National Lakes were my favorites. Although a lot of dirt was moved at Senator, it played more like a links course than the others and I liked the difference. Grand National Lakes was a more traditional parkland course and I liked the variety there. I’d go to Capitol Hill and Grand National again and skip Cambrian Ridge, which was a repetitive slog of hard holes featuring tee shots into valleys followed by long uphill shots into well protected fortress greens, RTJ like but not enjoyable. When I went it was a good value with affordable lodging onsite or nearby. I haven’t been back, and that is probably due to my affinity for a place called Bandon, which is so much better golf-wise.
