Behind the Firehall in Perdix was some of the best summertime smallmouth and panfish fishing in the world at one time , from reliable sources , folks who had the3 ability to go anywhere in the world to fish........sorry for getting off track the but 1wt saying Perdix brought back some great memories. I don't own a yak , but i do own a small inflatable raft , Sea Eagle , six different air chambers with a plywood floor , which make it possible for me , i'm an amputee missing my left leg below the knee , to stand up in it comfortably. Greenhouse Park in the Riverside area of Johnstown in western Pa hold an annual event tthat the closest thing i can compare it to is our JAM. There is a whitewater park there , manmade on the Stonycreek river , agreements for water releases from 3 different impoundments. Folks come from all over the world. I met folks from Australia , Russia , even China. If you really wanna see the whole scope of what's out there and learn more than you will ever use , i would try to attend one of these "JAMS" the thing is free if all you want to do is research , or you can camp there for a fee , they have the hook ups for RV's i think , and the crown Jewell for the hard core , OHIO PILE............heh........is about a half hour to 45 minutes from there. HAPPY FLOATING!!!!!!
