I picked up a MAK a couple of months ago and have found the cover keeps blowing off. The most recent was this week while I was traveling for business (the wife was with me) and came back to a frozen cover piled in a corner and the grill covered with snow. I had placed a couple of items on each side for weight but it obviously wasn't enough. Has anybody else had this issue? Is there a reason why MAK doesn't use velcro on their covers like Weber does on their covers?
