Linda was able to gather a number of donations from local businesses to fill the bed of the truck with toys and gifts for the family!

Her favorite memory of the station was in 1996, when she and Doug were able to watch the station go through a complete remodel. She can recall her son Josh, who was two at the time, watching all of the cranes and excavators work on the station with amazement.
