Please note: there are lots of rusty nails, lots of broken glass, and lots of not-super-sturdy structures at this abandoned farm, which do present serious dangers. You will want some solid shoes and maybe a pair of gloves, and you will need to keep an eye out for dangers. Not recommended for kids. It's manageable, but pursue at your own risk!
