I've done numerous half mounts for clients and we always put a small base with some habitat that they are standing on, so it can still be hung on the wall, could easily still be done on you'r half mount.
Greetings all! I've been a hunter for 50 years, but only now planning a trip to Africa. I was fortunate and successfully bid on a couple hunts for plains game in SA later this year and next. Also a rare Native Texas (5th generation) and USMC Vet. Hunt safe y'all!
