Take a romantic stroll down memory lane with this adorable Valentines date night idea from Pink Pistachio. Start by writing down some of your favorite memories on little rocks and have them create a trail leading to your final destination. For your final stop, have a romantic set up with old love letters youve saved from past years to read together. You might even bring a lantern, hot cocoa, and tissues to wipe away the tears, as you remember all the sweet memories you have created with your spouse.
