Not sure if this is the place to ask this but.. My dad is gettting ready for retirement and he is looking for

My dad is getting ready to retire. He is a general contractor. He has plenty of money and isn't sure with what he wants to do for his retirement. He has a ton of land and there are no Drivein theaters around (anywhere around). I remember them as a kid and they were so much fun. I'm not sure why they all died off though. Does anyone know? Do you think this would be a good idea for his retirement? He could work the theater in the summer and become lazy in the winter. What do you all think?
