This is just pure wholesomeness. A grandfather built a rollercoaster for his grandson in the backyard and is absolutely adorable. Also, it's the best of every situation. No lines. Clearly little man doesn't have to worry about if he's tall enough to ride. And most importantly, they're at home socially distant from everyone else whom of which probably don't have a personal rollercoaster. Chances are that'll be fun even after the pandemic too.
