If you are from the South, then you will find that the red is often runnable. The gauges are colored with a more Rocky Mountain perspective. Most of my boating has been in the SE, and I must have run Bailey ten times under 200 before I learned that that was considered by most to be unrunnably low. I now know it's way more fun with bigger water, but I still would go down to 165. Did it at 145 on accident once too, all the drops were good. Last year someone posted ultra-low water pics of a Gore run (450? maybe 250? don't recall) and it looked so sweet - all boofs and east-coast style creeky rapids. Ed Hansen has posted a few times that the Numbers are still fun down to 450. I actually think that 700 on the Numbers has much better play than 1000, 1500 or 2200.
Join up, suckas.
