I think the thorn problem last year was caused by sandbur plants that were allowed to go to seed and then were spread all over the trail when they were mowed. I saw DNR out early spraying herbicide so hopefully that and some mowing before they produce seed pods will prevent last year's problem. In any case they won't be producing their thorny seeds until later this summer so there shouldn't currently be a problem.
