swamp we live in the south and the only thing i cansee inthe advantage of inner covers here is another place for betttles to have another place to enjoy. every beekeeper i know down here use migratory. i have a few that i use when i run out, but as soon as i go by with an extra in my truck, i swap it out
Interesting, Bud, thanks for the feedback. Around here, the limited yards that I've seen (only a few hobby/sideliner yards) use pretty much telescoping tops and inner covers. In studying equipment I came to the conclusion that the migratory tops (for a stationary yard) worked well for dry climates but the telescoping tops worked best for wet climates. Granted, we have some dry times around here, but we also get some heavy rains and wet spells to come through. Apparently the migratory tops work ok in sealing the tops, otherwise why would folks use them so much...and they're much less expen$ive. I'm definitely game at trying them, though my mentor might raise an eyebrow (he already has a few times so he's use to it

).
It seems without a frame work going around all the way around the top that the top might warp. Are there any issues with that? Got any tips on using them?
Thanks!
Ed
