Last time we did this it was a weekday which worked out really well in terms of activity on the course.
We did a small one a few months back and started at WW and then went to Rosedale Down Under then Up Top (6-18). We were going to do Shawnee Mission Park after that but were blasted from the early heat and lack of electrolytes.
This time I think WW, Young Park, Legacy and closing it up at Swope. That kind of brings us up North then out east down southeast and then back into the city for all you cityfolk. It adds a little drive time too so you can HYDRATE.
