With the concerts at Rancho the river should be FULL of drunks, me included. I ran the pump house to state bridge twice last week. It is running pretty fast so its only about 30 mins on the river before you dip into the canyon there. Neddleseye is at the bottom of the canyon, as mentioned, stay right, there is a large rock right in the middle that you have to avoid but its actually way easier to run it at high water.
Yarmony rapid is a much bigger deal at this water level, but still really easy. Its a ways down the river from the canyon and you can hear the rapid coming as you barley move on the still water before it. After that its actually pretty boring, but a fun booze cruise. I recommend going all the way down to Statebridge bc the section from Rancho to SB is fun and only 4 miles.
Shuttle is through rancho and they have a sign up sheet hanging on the door at the little shop there, just sign up and they will move your car even if you don't talk to someone. However it is super super easy just to shuttle your self and hitch hike back up. Lots of traffic on the road and the river. $35 from Pumphouse to Rancho, $45 from PH to Statebridge.
