Sure! Here is what I wrote off the top of my head to the Director of Parks:
Mr. Redman,
Good afternoon, I located your contact information on your website. I wanted to reach out and inquire what the current rules and regulations are for Metal Detecting in Chaska City parks. This is a very fun hobby of mine, and most items are found within just a few inches. I dig in a way that lives little or no trace of anything ever being dug, and also throw away all garbage that I dig up. I am very permission oriented when it comes to detecting, so I wanted to reach out and personally ask if this is allowed in Chaska parks.
Thank you kindly for reading.
Jon
And here was his response within 1 day:
Jon,
It is fine if you search in city parks per the conditions that you follow as indicated in your email.
Thanks
