I realized having not written this review in almost two years, my review style has certainly grown up. Haha ... but that doesn't make it any less exciting that Lincoln Park Zoo is F R E E. Yeup, you heard right, it doesn't cost you a penny to visit this awesome zoo filled with interesting and cool exhibits and animals. It closes at 5 PM on most days but again ... it's free!There are lots of stores in Lincoln Park Zoo as well so you can buy those usual stuffed animals and other nifty souvenirs to go. There is an aquarium and you can see penguins and all the normal animals. Make no mistake, this is not just some zoo that they decided to put some animals at and no one takes care of it. Its very well maintained and rivals some of the best zoo's in the US. All this for free makes it a five-star attraction for me.
