It's just the way it goes in life. 5 years ago I was like wow, that dude is tier 4 Bell Labs. Now I can show them a thing or two. But I asked some really newbie questions along the way.

2 posts I see all the time are K&N and mpg related. I don't think there's anything wrong with someone asking it again. Things change--like there was a debate over regular vs. super unleaded and the $$. It was an issue 6 months ago, but today reg is 1.479 and super 1.539. Obviously I think super is worth the extra .06, but maybe I questioned .20 cents.
