What's the difference between 2 and 100? Nothing, IMHO. The challenge is curving the line back on itself. I have no doubt that one could string as many ramps together as one liked. I seem to remember one industrious fellow doing 3 or 4. JLN's site is like a mouse warren, keep poking around and you'll find more. K.
