If you're looking for something to do outside bright and early on New Year's Day morning, with a group of warmly dressed mostly friendly people (sure you are!), there are "24 guided hikes, 2 mountain bike rides, and 1 horseback ride" planned for the state parks and forests this New Years day 2018. http://www.state.nj.us/dep/parksandforests/parks/first_day_hikes.html All events are free, but some require pre-registration so read the descriptions. Some of the hikes allow dogs. (And in my experience, when they allow dogs on a hike, there will likely be as many or more dogs than humans.) Because nothing is assumed these days, the instructions say that mountain bike rides require you bring your own bike, and horseback rides require that you bring... a horse!
