Replying to Does any specific feature just scare you?

Give me urban, cliffs, chutes, kinks, transfer gaps, etc and I'll do what needs to be done.  But for some reason, Rainbow rails just freak me out.  I sit and ponder hitting them while people make laps around me before I finally man up and hit them... only to find out that they're fine and really not bad.  Yet, come a new rainbow and I'll go through the same system of anxiety again.  Nothing else, just f-ing rainbows.  wtf?
