When you say, "reasonable public access," I assume you're referring to CRP ground.  I did not know that.  Yes, in SD, some of it goes into the WIA, CREP, CHAP, etc. programs.  But do I have reasonable access to the vast majority?  Absolutely not.  The highest bidder does.  In my experience, that's usually the local ophthalmologist. 

 Maybe that's reasonable??? 

  (FWIW, this is one reason I briefly considered ophthalmology as a career path.  But since I chose otherwise, it's now one reason I avoid patronizing ophthalmologists at all cost.)
