USAC and I will be at the River Cleanup & BBQ this Saturday. Would love to see & meet you there. We will have a table shirts & stickers available for donations. 6/23 10am-3pm, meeting at the put in near Henifer exit in 10am and BBQ at the take out Taggart exit allong I 84 on the Weber River. If you have a kayak, or pontoon, or river worthy flotation vehicle you can float along and clean up the banks as you go. If do not have a boat of sorts you can still participate by walking along the river and banks and clean up that way too. What info I have is from our friends at http://www.utahwhitewaterclub.
Oh and one last safety note. If you are floating, please do remember to come prepared with your own personal flotation devise (PFD).
