This outdoor mall is perfect for any last minute shopping! You can also find tasty restaurants around the area that are worth checking out!
This place has a really chill vibe but their beers are amazing! Make sure you try their Cactus Jack!
For the adventurous ones, you could travel to Angeles National Forest about 30 minutes West of Rancho Cucamonga. You could go on a hike and enjoy nature... or jump off a bridge.. your call. Please no broken legs at the party!!
