Anyone have any experience with either of these last season tris?

I am going to be in southern Utah in the fall a couple of times on business so I am looking at two potential races to pick up a late season Oly.

One is the Kokopelli Tri at the Sand Hollow Reservoir in Hurricane UT in mid Sept. The other is Powell 3 Triathlon Challenge at Glen Canyon National Park in late Oct.

Have you done one or the other (or both)? What was your experience? What do you think of the course? How well is it organized? Any issues with local lodging? Any preference and why?

Thanks in advance for the feedback.
