There is seldom a shortage of crowds at the Boise River Park, from surfers to kayakers and boogie boarders. But like any resource that needs to be shared, there is seldom a shortage of conflict, either. This summer made for some rough waters as Boise River Park wave technicians tried to keep both surfers and kayakers happy. Both user groups rely on a very different setup from the adjustable wave, and when area kayakers felt it catered too much to area surfers, well, Boise Parks and Recreation didn't hear the end of it. The learning curve for new wave technicians to create a fun and surfable wave through various water flows didn't help, either. It left a lot of river-running enthusiasts leaving the park shaking their heads.
