Yes! You can make obstacles pretty easily, too. I made a rail with a drawer pull I got at Home Depot screwed together with two blocks of wood. I use it on my desk all the time.

The cool thing is, you can fingerboard on almost anything. Get a stack of books and you can make a stair case. Get a piece of a granite counter top sample and you can make a ledge. You can use a bathroom sink as a skate bowl. There are also lots of companies making fun obstacles with different materials. The possibilities are endless.
