Just taking the easy route and dragging everything out because the show is popular. The storyline hasn't really made any progress at all since Rick first met up with the group in the first season, they've pretty much always been in the same situation they were in at the end of season 1 at the end of every following season, and when it looks like they have some kind of direction to take it in they always find a way to get out of it.

I bet they either drag out the travelling to Washington into next season or they will get there and nothing will happen, and they'll be in the same situation they've been in for the past 4 years of the show.. Stranded in some new place with no plan.

It's 5 seasons in now they really should be planning for an end.
