Are these good seats at the coliseum?

I'm looking at buying some tickets in section 20L Row 34 for the 49er game and bringing my wife and kids (10 and 13). Anyone sit near this section? With this being on the visitor side, should I expect to have more 49er fans around me than on the other side or will I run into that chance no matter what side I'm on? Not sure if the niner fans will travel well when out of playoff contention or not.
