LOL,The triangles are to cut down on on drill holes and speed up cutting.I'm always interested in short cuts.Charity, your right i do way to many free things way too many ,but GOD matches me dollar for dollar somehow!Orders, orders,nothing lacking in that department.just no $ attached to it.If I could stay out of stores and not meet someone that looks like they need their name i'd be ok. The little money i have would be another reason to stay out of them,I go stir crazy not getting out ,so I ride the handicap scooters in the stores to kill time and tell jokes ,make someone laugh and tease the girls. I do get in trouble at times, but somehow I get out of it.All's fair in love and war,lol
