Until you start getting calluses on your bum, it might be a good idea to just pick a general direction. Then, ride 'til a little less than the amount of time is used up and then turn back. You can have more fun without the stress of having a definite destination that you "have to" reach, and you will have the flexibility needed to branch off and go exploring.

Let's hope there's intelligent life somewhere in space 'cause it's buggar all down here. -- Monte Python
