Wasn't sure where to post this, so if I got it wrong I apologize.
I've got to head to Michigan tomorrow and I'm thinking of checking out Mounds Off Road Vehicle Area in Genesee County (http://www.geneseecountyparks.org/pages/MoundsORV
). The regulations say that vehicles must be equipped with a USFS approved spark arrestor. Is this something that I have to add to my stock muffler, or does the muffler qualify by itself?
I've been searching around online and haven't been able to find any clear information on what is required so any help would be greatly appreciated.
Also, they mention that helmets and eye protection are required...is that only for ATVs and open vehicles or will I still require a helmet for use with my truck?
