I did the Ayers Landing trip this summer (at Rambler's suggestion - thanks). Took the short hop which puts you in just south of Rt. 52. That was a nice 1/2 day float trip. Other trip is up to Sheridan, which is more like an all day float. I went on the weekend and yes there were lots of people, but not many fishing. So I could pick my spots. Since I brought my own yak it was like 30 or 35$ which I thought was reasonable. Plan to do the longer trip this year.http://www.ayerslandingcanoerental.com/index.html
Looking forward to trying his other suggestion - a circle trip, unique for a river.
Sit-on-top (SOT) or sit in Kayak? I bought a $200 end of year special SOT 10' from Walmart 2 years ago. Be careful about your center of gravity. My seat is a thin piece of foam, so I use a PFD seat cushion, extends the time before I need to get out and stretch. But it does change the stability.
I mostly fish the Fox, and find the yak a nice change from shore hopping. Either with a buddy or getting my wife to help with the shuttle service, I drop a car at the take out point. Shuttle to my entry point upstream. Enjoy a nice float and fishing trip, without having to paddle upstream. This gives me access to islands and stretches only able to get to with a wade. Often I beach the yak, then work the area in my waders. Able to fish much more area in one trip. Avoid spots which receive too much shore pressure.
Cooling lakes are only for motor boats. I think they don't want you to get caught in the forced circulating current - Liability thing.
There are lakes around the area which are great to fish. That's where the cradle comes in. Often parking and entry point are a ways apart.
Summer of 2019, also did a nice stretch from Oswego down to Saw-wee-kee park; which is ~ 1/2 mile downstream past the Orchard Rd bridge. Plan to do that again.
