It's probably been discussed elsewhere, but short answer; it would be awesome if it weren't for private property issues.
There is one notable drop (class IV maybe) immediately below the open space park. It often has a barb wire fence strung across it, and sometimes wood. Then there is some nice cruising. Miles of scenic beginner whitewater (class II), with zero access. Some no trespassing and more blatant hate-boater signs mark the town of Pine. A few barb wire fences can be an issue, or you might be able to duck them, or you might be able to portage and get arrested. After a one or two mellow class IIIs, you arrive at Buffalo Creek where you can takeout without getting yelled/shot at.
It's basically a fantastic beginner run (with a portage of the first drop), that isn't feasible thanks to the property owners in Pine, CO stringing barb wire across the river. If more kayakers ran this section, it would probably become more navigable.
