I was there for the first opening of the Texas Giant 21 years ago, I think we were in the 30th car to go up.  
  
My plan is to be there friday morning too. 
  
When the Giant first opened I believe they let Season Pass holders get in earlier to ride it, but it's been a while.  I guess they won't do that this time. 
  
Thanks to all for the informative and helpful posts.  See ya'll friday!
