first of all that it's infinite and non repeating, meaning that in pi there is every number, every combination that will have to do something with my life. and if you convert this number to ASCII encoding you will get every name that will as some point of your life associated with you, wife, kid, friend, name of bear you drink, name of place you go for summer vacation and so on, absolutely everything
another fascinating this is that actual length of river is nearly equal to distance from start to end (straight line) times pi
so if actual length is A, and distance from start to end B
A =~ B*pi
it needs to be multiplied somewhere form 3 to 3.14 but never exceeds pi
enough reasons or do you need more?
