They just quietly ditched them all by 2018. Call me weird, but that irritates me. They should have done something with those. A keepsake, memorial, anything, they could have sold them or given them away.....anything would have been better than "Well, let's just let them rot and when we need to land, we'll just turn them into mulch or something". I have a whole 'round' from that stack with 'bonfire' burn-etched into it. It means a lot and it would mean a lot to a anyone of that age that worked on it or was ever involved.

I guess they figured enough time has passed and enough new students don't know what it was for it to matter.

I have a few piles of oak at my place that are at LEAST 25 years old. Oak doesn't 'rot' like soft wood. The bark will rot and fall off, but I have sawed open logs that are 20+ years dead and they are solid as hell inside.

Those were either set all on fire after being bulldozed into a pile, which is ironic and irritating that no one got to be part of it, or they were turned into mulch and spread out across that yard.
