Bill, if you’ve been out of the saddle that long as a CFI I would suggest you go find a flight school and brush up on the regs and your flying skills before you take on the Drifter. Attend an AOPA Rusty Pilots seminar, it’s free if you’re a member and counts as the ground portion of your BFR. Ask around and try to find a Light Sport instructor. Finding an instructor in your area willing to check you out might be tough sledding. Assume your Drifter is registered as an EAB. You might have to find someone with something like a Challenger and get some stick time and take on the Drifter on your own. Good luck and be safe.
