For those who are more handy than I:  How would you go about attaching a gazebo to existing concrete?  I've already decided I'd rather drill into the concrete than do some other not-so-discrete weighing down solutions that wouldn't require drilling into the concrete.  We plan to keep and maintain this gazebo and don't need it to move.

Probably the most recommended solution I've seen so far is Wedge Anchors with a Hammer Drill.  What are your thoughts?
