October should still be pretty nice. Just looked at my riding from last Oct and I was still getting in quite a bit... even did Bachelor and McKenzie Pass towards the end of the month. Assuming you don't upset the weather gods you should have 60's and 70's... well... mostly 60's but definitely come prepared for cooler weather cause you just never know. The car free day at Crater Lake is pretty cool, I just did it yesterday and it was nice not having to deal with cars for half the loop... although in the theme of unpredictable fall weather the car free weekend last Sept was a total bust as Crater Lake was completely socked in with rain and clouds.
