There was another drive- in in Monroe County. Long ago. I don't remember the name of it but it was located at Ida Corners. On the on the Northwest corner of Ida-Maybe Rd and S Custer or M-50. I think it went up in the mid-1940's, right after WW II. And I think it had one big speaker rather than speakers in the cars. I never went there as I was too young to drive but I went past it many times and always looked for it as it was a novelty at the time. I hope this is of some interest to you.
