Sourkraut,
As mulecreek stated, you will get your bucks, so I'd focus on defining what "a successful hunt" means. If I thought an antelope hunt was going to be my last, success would include spending as much time as I could, just looking over the country and the bucks it holds. I'd also avoid the opening weekend crowd and chaos and not try to beat everyone else to the "best" buck in the unit.
A quality "successful" antelope hunt for me would include glassing lots of bucks and maybe even holding off hunting until later in September when the bucks start rutting. I'd try to find high spots to glass from and then choose really good bucks to try to sneak in on.
My favorite antelope hunt was just like that! It took place several years ago with my son. We loaded our truck with all our gear and a tent and then looked over bucks all day for several days. When the sun started to set, we would pitch the tent, cook dinner and hit the sack. The next day we would get up, have breakfast, pack up and head out again until nightfall. "Nomad hunting" Success for us was a great time, a book buck for my son and a memory we still talk about.
So if any of that appeals to you, give it a go and best of luck to you old farts! :0
(I'm only a few years behind you)!
