Hi John and all

Wind is your problem.  I have used  screened bottom boards open to  
the ground on most of my hives for several years.  My hives are  
located in a deep valley beside a river that flows all year so  I  
figure that moisture is my problem.  I shovel snow around the bottom  
of the hives when it gets very cold(-20C to -30C).  I think that if  
you can protect your hives from  the wind blowing past , you can  
leave your bottoms open.
