I took my 14 year old son and 3 of his friends – all first timers – and I was really worried they were going to get hurt as of course they had to sign those scary release of liability forms (possible “death”).  And as it was their first time (I’ve done it before though), I know how aggressive it can get.  BUT THEY DID JUST FINE!  The fields were amazing, as well as the refs.  The refs knew whether or not they should be on the beginner, intermediate or advanced fields and had no hesitation directing them to the correct field.  I was happy they were all good after a couple of rounds to make it to advanced  😉
