While I agree that the city of Atlanta, and the north metro areas can be expensive, the Atlanta metro area is actually quite large and there are more affordable options in close proximity to the west, east and south. One does not need to live in Milton or Alpharetta to enjoy this sport. I think people believe “Atlanta horse scene” is synonymous with these two areas, but it’s not.
As for commuting, Atlanta is largely a technology services town. Several years ago - long before COVID - companies were offered a tax credit to initiate a hybrid work solution to help reduce the number of vehicles on the highways, which remains in place for many employers today even though the credit is long gone. Sure, some jobs require you to work in a physical location, however, many do not, which has allowed people to move further out. As a result, smaller towns that were previously considered “too far out” are becoming more interesting to developers. I know this because my SO is involved in development - I actually live in Atlanta and have first-hand knowledge of the current state here and what areas are attractive to developers and which are not - the new development action is largely in the north.
As for the cost of this sport. There are more affordable options other than living in North Fulton (Alpharetta/Milton) and choosing to keep one’s horse there. You could have the same commute into the city from another county to the south and your money will go sooooo much further. It comes down to choice. There are talented trainers in all parts of the metro area serving all levels of clients.
Also, the Atlanta metro area actually has 3 tiers of competition serving Wills Park. Rated, GHJA locals (your HJ Fox, Elite, CCO, and HSV shows), and then a tier just below that which is even more affordable, with less expensive stall fees, lower office visits fees, lower class entry fees, and run as a single day show.
I think Atlanta is a bit of a unicorn to be completely honest with you. I don’t know that it’s because we are “lucky,” though. I do think it’s because the equestrian community here is doing everything we can to pitch in and make it happen. It’s not luck.
I also think the Atlanta-metro trainers have gotten pretty creative (which is the topic at hand) about how to keep people engaged. Some programs let their lesson riders jump a bit higher than 2’ and then offer show leases to those riders. Some programs have partial leases. Some have lesson and show packages, where the monthly cost reduces if you commit to showing.
