Thank you guys! I knew you'd have some good things to try. 2frustrated, no rush, but when you have time could you post a pic of that? I'm having a hard time visualizing that stretch, although it does sound like a good one.
I used to do a version of the standing-on-a-step thing, with the edge of a curb, when I used to have a door-to-door sales job and would be walking all day. I'd forgotten about that.
Again, thanks so much you guys!
Oh, and Silverbirch, nice to meet you!
