New NO BIKING signs at Sunken !meadow State park

There are new signs that say we can no longer bike on the roadways which means they only want us on the walkways. The walkways are in disrepair . We need to use the roads. Why are they doing this to us? I have spoken to other cyclists and we will fight this tooth and nail...It seems like a new way for the town to ticket us and fleece us for more money.
