Yay, we are faithful date-nighters too! Occasionally we go out for fabulous dinners but mostly we keep it simple also. We bbq, watch movies at home, have bonfires on the beach, go to Dodger games, rent pedal boats, visit museums, etc. It's all easy, close, and inexpensive.
There is a park we've loved since we started dating. We hike up to the top of the hills where there is a killer view of L.A. and picnic. It always grounds us to go somewhere we frequented when our love was new and we had nothing. Do you guys have a place that is special to you like that?
