Early seminars were to let the students of the school owner or teacher of the students( a rare chance to meet & train for a day or 2 with the teachers teacher.)This fast became away to let those who know of the masters or trained with them or meet them go tho circvuts & show what they know or dont for money>Now when people like Wally Jay -Dan Inosanto-Arsenio Advicula-Started doing not only nation wide but expand to over seas.Then Teachers from all kinds came out with claim & did seminars.Some thime the pioneers plan on good ways, but others jump the band wagon & what started at $500 for a day grew to $1000- $1500 per day.When I do a seminar I try to giver the people a feeling of original traing days & lenght of time we did it per day.My seminars Have 2 - 8 hour days.Too long you say.No dont you go to work or xchool & get the full day.Hence Full perspctive of what is done.
