Metal detecting. Lots of fun and healthy exercise. I have a $1200 White's unit with a lot of bells and whistles that are SO wasted on me. My grandson's Garret 250 can be had for $212 on Amazon, is lighter, easier to set up and use, accurate, and perfectly adequate for the average hobbiest.
Quilting. DH bought me a 3/4 size sewing machine, so now I can piece all my blocks in a couple days, then hand quilt them in quiet times.
I also do camping videos on YouTube. All I need for that is an old Kodak Playsport. Not the best camera in the world, but it's small, water and impact resistant, and has an impressive battery life per charge. I have a lower end Nikon Coolpix that takes better video and audio, but it eats AA's like they are free and is not weather or impact resistant. If what you are looking for is the fact that Rainbow Country CG in Cedar Key has an enclosed dog exercise area and a cleaning station that will hold a 600# hog, or that there is no restaurant within walking or biking distance of a particular CG in St Augustine that is open for breakfast but it does have a free boat ramp and a bait shop, you aren't really going to reject my videos because they are not professional quality.
