We don't always appreciate how the bike paths in Columbia were designed to not cross major intersections. I can go from Savage Park to the Columbia Athletic Club, a ride of about 10 miles and only have to cross two streets. The B and A trail in Glen Burnie makes you cross some busy roads like the one below.
One of the interesting features of the B and A trail is the sun and planet demonstration with representative sculptures. The Sun sculpture shown below starts the demonstration and the sculptures representing the planets are placed in relational distance to the Sun sculpture.
