Does it cost to have a memorial there

Thank you I tried but no answer no at a shelter my sister in law loved the out doors and were from that area and the park was first thing I thought of thank you

So do you mean in the Shiloh cemetery or do you mean having a group of people at one of the shelters? If it's the latter, just call the park because you'll need a reservation which is approximately $50 for the day.

Youd need to call the park.
