I've never seen one, but have read about them. They don't sound like something that would intrest me, i don't have room to store my ten frame equipment now,can you use some of the standard ten frame equipment with the top bar hives? This reminds me when i ask my daughter=in=law if she like turnips, she said (oh my gosh no), i ask her if she had ate any and how they were fixed, her answer was No i've never had any? So who knows i may like them if i tried them. I'm game. Jack
Top bar, Warre, and other such hives are becoming more and more popular, especially amongst those interested in more 'natural' type beekeeping and foundationless beekeeping. You should definitely have a forum for them, as the management of them is quite different from Langs.
