Last minute planning. What to do on Valentine's Day?

The city of Davis, also known for their UC Davis campus, has an Arboretum that runs along the side of Putah Creek, estimating about a 3-mile distance.

It was interesting to see that the students here in Davis started a trend of love locks on the small fence of the overpass bridge, similar to the London bridges. This would be a great place to take your significant other here to place a love lock on the fence. It may be silly but this is a great valentine day spot if you still have not decided what to do yet.
