[ARDF] Orienteering vs ARDF

[Marvin Johnston]

I have always compared an ARDF course to an orienteering Orange course.
It would seem that the Green, Brown, etc. courses are more technical in
nature without the catching features, etc. that are used on the Orange
course. And *I* consider the signal strength and direction to the
transmitter as an *excellent* catching feature :). 


What comparison would you other orienteers make regarding courses?
