Do they allow Metal Detecting?

For non-commercial non-estructive use by curious boys and girls? Yes

I pretty sure they do

Yes

Yea but don't destroy the land

Pretty sure you can metal detect on any public property

Not sure about this

I wouldn't bring in a backhoe, or dig huge holes. There are trails in the West side that would be good locations.

I don't think they do.

I believe the grounds sit atop an old landfill. Pretty sure they don't allow digging because of that.
