Hope it's okay to plug a business here.
For those of us who don't care to clean a skull ourselves, Ryan Hein at rhinoriginalz who's associated with Steve's meats in Arvada beetle cleaned the skull for my boy. Price was $105.00 which beats everybody in town that I could find.
It takes a good 6 months so it isn't a fast turnaround but the price is right and the results are very good.
He did a nice antelope and this deer for us and I hope to give him more business in the future.
