NickDG,
Which individuals have the right to decide who enters BASE? Someone with 200 BASE jumps might say you need 1,000 skydives before you make a first BASE jump, someone with 500 BASE jumps might say you need 5,000 skydives, someone with 1000+ BASE jumps might say you need 10,000 skydives, … different people have different opinions based on their experience.
If you try to restrict access to BASE too much I think you’ll get more people who find other ways to enter it on their own without any (or little) instruction and perhaps without correct equipment. Which is more dangerous?
