San Diego Electric Railway Association has invited bronies, and railroad enthusiasts to tour the historic "Station and General Office, California Southern Railroad". There is no entry or tour fee, however, the building which was built in 1882 is maintained partially by donations of those who visit it; therefore, we encourage all who attend the meetup to provide a donation.
Here is some background on #[masked] of the National Register of Historic Places (it is also California Historical Landmark No. 1023):
Afterwards, join some bronies on a nearly 10 mile hike down to the (https://www.meetup.com/SoCalBronies/events/241710156/) Imperial Beach Pier (https://sdfish.com/san-diego-fishing-piers/imperial-beach-pier/), where we may have an early dinner on the pier (http://www.thetinfishrestaurants.com/the-tin-fish-restaurant-imperial-beach-ca-on-the-fishing-pier/).
