Ethan's fieldtrip to Marengo Cave IN went great. It was really cool I had not been there in over 20 years. The formations are so interesting and the history of the cave is intreging. All the kids asked great questions and Ethan got one of his pennies to stick to the ceiling of the cave and was so exciting. I handed out like 20 pennies to all the kids and I don't know how many stuck or not but it was a lot of fun. The cave was discovered by 2 kids (a 11yr old brother and 15 yr old sister ) back in the early 1800's who crawled into a sink whole and explored it by candle lite. If you ever get a chance to go I recommend it! Lots of fun.
