I have to ramp up to a height of around 36"-42" for a scene. This will not be a wheelchair accessible area. What kind of incline can I use that is still comfortable to most patrons? I may also make it narrow in parts on the way up to play on claustrophobia fears. On the way down I will probably hang stuff in the way to create darkness before the next scene. I was thinking about a 2/12 slope ramp? 1/12 seems flat and 3/12 might seem like your out for a hike. Has anyone ever used more lineal foot on the accent side of things and less on the descend or vice versa?
