As you've probably heard, we're up to our necks in anniversaries around here. Our trade show, LDI, is turning 15. Our sibling publication, Entertainment Design (previously known as Theatre Crafts and TCI), is 35. Right in the middle is Lighting Dimensions, which is now a ripe old (for magazines, anyway) 25. This is usually the point where Jackie Tien chimes in that I've recently turned 45 — but if that's her game, she can get her own column.
