Sketchbook ramp obsession

I found a couple of old sketchbooks that I used to scribble down ramp and transition designs when I thought of them.
They are literally cover to cover full of drawings and descriptions of ramp and pool designs from a period when I clearly could think of nothing else!
Of course much of it is utter toss that would be unskateable to anyone, but looking back through these books I've found a few gems that could work out real good.

What goes on in my head...I have no idea.
Here's a small example of what can be found on the pages within.
