Installed product on a concerte deck in backyard in June 2005. Secured frame to cement thru pre-drilled holes at the base of corner panels. Installed two feet long ground stakes at three corners. Per "WARNING" instructions #8 remove canopy during severe weather conditions. I personally have only removed the small canopy once to allow air to "vent" during a windy period. I am located in eastern section of North Carolina.****I am in the market for spare a canopy, mosquito netting and lower fabric sections. I can be contacted via: jabez@verizonmail.com
