Yes, that is what I do. I know I am being unreasonable in my fear because I watch DH mow the exact same areas and can see that the mower remains stable, etc -- but when I am actually *on* the mower logic goes out the window and it feels way steeper than I know in my head that it is.
My wife is the same way. She's also lighter than I am so she has a little bit of a good point.
