I tried a seventy yard fg in high school and had two refs on either goal posts...course i had made a fifty seven and a sixty one yarder already....ball hit the cross bar...
seems like that should break hte sixty eight yard record since it actually hit the cross bar...haha...
you can see video of the sixty one yarder at this website....
