i haven't been to a formal class on beekeeping, but i did get a chance to assist working some hives with experienced beekeepers in the beginning. i have done a fair amount of reading, and i have learned alot from the good members here on beesource.
in the end though, for me, and has been posted above by others...
nothing compares to the time spent with the bees,
and maybe more so the failures than the successes.
