My only Friend, The End
Things learnt from taking two 9 hour car trips in a matter of days:
The above dust (yes dust, not fog) should eliminate any doubts you may have that this country is currently experiencing a drought.
An unlimited supply and variety of snacks is compulsory. A choice between nuts and fuitcake doesn't cut it.
An unlimited supply and variety of music cassettes is also compulsory. This should include a best-of The Doors tape. It should not include bad 80's mixes from the $1 op-shop bin.
Travelling with a hyper-active stress-head is not recommended.
Lower back pain from driving and feelings of being overwhelmed by the hustle and bustle of Melbourne means you are probably getting old.
