I was not asking for 
  anyone's advice on the subject, I am well aware of all the ramifications good 
  bad or indifferent of riding pregnant mares, I have had many of them over the 
  50 + years I have owned horses, I was simply trying to clarify a rule point 
  for someone asking on RC, And asking for my on info about the rule.  
  
   
  From my point of view---when a general 
  question is asked, there are many more people other than the poster who are 
  interested in the answer and possible "spin-off" information.  I 
  think, for these people, it is good that anyone responding add as much 
  information as possible---even if it appears to insult the intelligence of the 
  original poster.   Most of you do know these things--OTH--a lot do 
  not so it is good to take every opportunity to add information to the "general 
  fund".   IMHO  Claudia
