Ah. Even better. Thanks for correcting me.
I thought there was another park within 1.5 hr west north west from windrock.
I think the challenge is to find a group guide for each park that knows what trails to run and in what order. Not knowing what to run and what to skip and not back tracking can save a bunch of time.
Example @harlan:
We start out and run trails in this order.
Pinball
Railbed
Fish fossil
Lower rock garden
Killin time
Lower profanity
Upper profanity
Grape vine
Middle rock garden
Mason jar
And then go look at lions den.
That's a good day of wheeling, usually break for lunch at middle rock garden and are done before dark if no major breakage.
Having never been to all of those places and wanting to do a trip to all of them at once, efficient leadership at each park would be crucial.
I think work together as group to fix broken items fast and keep moving. If parts can't be found to fix or can't be fixed then get them off the trail and then see you later.
