Wow, cool story 8) Its a small world, isnt it.
No, i dont know of any amusement parks there since i lived there. From the sound of it, it had to be in now what is Washington park, and i bet its where the fedders alley section is.
Things change to say the least...in this case for the worst, i'm sorry to say! That area, if it is old amusement grounds, is probably the worst area in Michigan City now. Totally crime ridden and a crack head paradise! I dont know if i'd want to detect there now, and if i did i would be carrying gun. This area now borders what they call the "Canada" section of the city. Dont know why its called "Canada" and never did, but it's the central point for most of the homocides in the city.
Great story, DD. 8) It's nice to hear of the good old days had there before i was born and to think of the place in a different light, instead of only for what it is now. HH. 8)
