How do theyy check your age at the EDC rave?

well last year i went in 2010. i was 14 years old and they require a legal guardian with I.D and they must be older than 18 years old. so you can come in with an adult they will let you in.sadly this year in 2011 they no longer allow minors inside due to an incident of a minor who died of an overdose last year. so minors can no longer come we are banned from the raves now :(
