His name is Steve Dobbs and to his Grandkids he is a hero.
The former Boeing aerospace engineer was inspired by his kid's love of Disneyland and devised his own series of rides built in his backyard and called it 'Dobbsland'.
It includes a Thomas The Tank Engine and Frozen ride.
There's even a roller-coaster, but erm we somehow think it's not as scary as the woman using it at the start suggests.
