It’s usually on the first Saturday of June in rhinelander WI, it doesn’t cost anything but you can donate to support (they suggest $10) also you have to account for gas and a place to stay which you can stay at a campsite there but it cost money also it goes from like 10 am to 6pm
You don’t have to but 100% you can if it’s small enough it’s fine if it’s a big siren you have to register it which I don’t know if it cost money to but I’m bringing my 2001-SRN for 2025 with one other special project hopefully
