Have you reached out to any facebook groups? https://www.facebook.com/West-Penn-Trail-315640345984/?fref=ts
Maybe start an email list and hang a flier at trail sites during the riding season? I think there's a board in Dilltown at the pavilion.
You may also want to consider contacting http://www.transalleghenytrails.com/
Let them know what's going on. Groups like rails-to-trails (.org) have mail lists and politically active sub groups that they could possibly put you in touch with. If the politically active groups that generally fight this opposition are unaware of the goings-on, that could be problematic.
I appreciate your call for help, but it generally is more productive to have specific targets/meetings/etc. Perhaps you can keep this thread updated when anything crosses your radar?
