I too am looking forward to Iowa Jam in March. While out of the state this winter I collect some 4 to 5 inch diameter bamboo. I hope to get some tips in March as to how to use it to back a bow. There sould be plenty to trade. I cut it just before the first of the year in Louisiana. It should be cured by March. It is just now loosing the green color here in Arizona. Any suggestions on handling and processing?
