CBH-in the past couple years our local college remodeled their “life science” museum and upgraded it immensely. It now contains life size elephant bull and several giraffes/rhino etc as well as new North American big game in extravagant dioramas. They even did a room with all of the worlds waterfowl and game birds with magnificent woodwork and glass to protect the mounts. Much of it was donated by private collectors. It was fun to see a museum older than I am upgraded and improved to modern day capabilities!
I’ve been in several professional athletes houses where they built special rooms just to house their trophies complete with mountains built right into the wall-it is surprisingly common among the wealthy and many of them are gracious hosts as well as serious hunters.
