City living has its challenges at times and there are times when it can be really aggravating. Then there is the good stuff, the moments big and small that make up the reasons why so many of us choose to love in big cities. Public transportation can often be a hassle but there is one thing that always makes my day. There is something about seeing a happy dog excited to be riding the bus or streetcar. It can put everyone in a good mood, like this fella I recently saw on the F Market heading downtown for a little adventure. So take your dogs on MUNI, just remember, they have to pay their fare.
