But to get back to the original point of this thread, IMO it doesn't make any difference if it's this years urine, or last years urine, because by the time we consumers get it it's already chemically broken down to urea.
Besides, if you think about it, it's not the urine itself that we are buying it for, but the PHERMONES that are (or maybe in fact aren't) in it.
On that line of thought, here's an idea that will make someone rich........If one could chemically isolate the phermones that we are buying the urine for, and market that in a usable form, then we could dispense with soaking ourselves and the woods we hunt in with what's basically racid ammonia in the first place! And the beauty of it, is that it wouldn't even have to be phermones from a female DEER!
Do you see where I'm going with this? Ladies, are you paying attention? [:)]
