Blossom looks intimidating at the scout rock, but it honesty is easier at higher flows. You can run it right at higher flows or take the traditional left line and miss the fence. I Like to start in the last good eddy on the left so I don't have too much downstream momentum going in, I make my ferry, set behind the big boulder for a second, and run the little drop. This will spit you out headed for VW rock. I typically go left of that, I tried to get to the right side of it one time and got stuck on it for a little bit. If you have passengers in the raft you may want to take paddles for the fish ladder. I got hung up in it for a little bit on my last trip, but we had set safeties along the way and they helped tug me off real quick to keep our large group moving.
I've run it in May, weather can be solid 48 degree rain for days. You may end up with 90 every day, be prepared for both. I've also had the level go up several feet in May, so keep a tidy beach and tie up your boats well.
Have a great time! I love the Rogue.
