Not really. The only other way would be to hitch hike and then you re not guaranteed to get there! Taking a bus isn t going to kill you. I would plan on spending some money along the way for food and sodas.
greyhound sucks. and that trip will take 48 to 72hours or more on greyhound. (greyhound is the cheepest way) but going bus. your boned if you wish to sleep. plus some places you have to watch for the crackheads who will try and steal you blind...best bet. Drive!!!!!!!! so you can stop when you want to. and it will be much much faster. but it will prob cost a bit more.
