I see two scenarios for future Africa hunts, the next few years and after the boomers are flushed out of the system (dead, broke or too sick to go). Presently, there is an oversupply of venues, competition is fierce and getting more so every year, hence prices are falling. This will only last so long. In ten years when the boomers are done, half or more of the outfitters and camps will be out of business, there will be less competition and prices will reflect a return to the tradition of only the well heeled being able to afford the cost. For the younger guys longing to go, the door may be closed by the time they've got the funds for a trip in today's prices.
This thought is what made me want to hunt Africa sooner than later. I hunted RSA at 29 for the first time, 31 for trip two, and 33 will be trip 3. I don't have a super high salary job, and have a mortgage, vehicle notes, wife, and a baby on the way. I wanted to see Africa while I could and while the prices made it very possible.
What did I do? Removed the frivolous expenditures. Wrangler jeans and khaki's over Levi's and dockers...Bulleit bourbon more than Woodford and only a couple cigars a month (also a healthier lifestyle I guess). Finally, one of the harder decisions for me personally, was limiting my firearm spending. If the firearm isn't going to be used for hunting, self defense, or a 'dream' piece, it isn't bought. No more, "too good of a deal to pass up" buys. Along with that, if it was in the safe and rarely used and not one of the above reasons or a family or sentimental piece, its for sale.
YMMV, but for me quality over quantity took over my head at 29. Big bore wise, I'd rather have 1 416 Rigby in the safe well practiced with loads for PG and DG than an additional 416 REM mag, 416 Ruger, 404J, etc, etc...but with a double to keep it company
. Nothing against those who do as I would LOVE to have them all, but I'd rather hunt Africa a few more times with my dad now, than have rifles sitting in the closet. I can always buy them down the road if the need or desire rises, but I won't always have the chances to hunt Africa with my family that I do now.
