Go down to the basement to find there is no glass on the TZ. Realize it must have been off for at least a few days (house renos happening and house is dusty - so not good for the pin). Want to put glass back on but can't find it. As I'm starting to yell up the stairs at my husband for leaving the glass off the TZ, I poke my finger towards the playfield and jam it hard against the new PDI glass which is in fact very much there.
