Once again the US Botanic Garden in Washington, DC has transformed into a holiday destination. There are models of monuments and familiar buildings made of dried leaves and sticks. There are model trains and regional lighthouses in another room.

High above the crowd several trains cross bridges made from tree trimmings and other bits of botanical cutoffs.
Careful cropping with the lens and some good timing can produce realistic looking action shots.

Here can be seen some of the lighthouses and Thomas the Tank Engine.
