Hey Mowermen, I'd have to say that travelling alone these days is never really travelling alone. You will always meet people on the way who are heading in the same direction and doing similar things. BBlaze is right being well prepared and self sufficient is important but if you have a desire to explore this great country of ours then setup properly and just go. If you want to get a travel buddy try some of the back packer web sites they're always visitors looking for transport just don't expect them to pay for much :).
Mate, 1988 i drove a sigma sedan to the Jardine in the cape by myself and i met people on that trip who are still friends today.
