Hey Pathfinder. i competed in the RMEF World Elk Calling Championships in Reno,NV and in Portland. i got into it via bugle magazine that the RMEF puts out bi monthly. they have the World championships every year toward the end of February. when i competed i used all mouth reeds and grunt tubes. for the pee wees and youth they give them 1min to produce cow and calf calls and 1min for Bull bugles. there are 7 judges behind a curtian on stage and they take out the worst score and best score to determine your final score. they start out on a friday with preliminarys and then the main bugling championship is the next day. its a great experience!
