What do you guys look for?

Hello!

I am an avid hiker in the Pennsylvania area. I do travel to other places of course, but primarily I’m im in Pennsylvania. I was wondering if anyone had any advice for things to look for as we start going into the colder months. I usually (in the warmer months) look for mushrooms and enjoy the foliage but both of those options are far more scarce in the winter. Any advice/tips/ideas will go a long way! Thanks!
