I love travelling on the bike with my special lady......or my wife if she cannot go,

but its interesting to see the thought process of a couple when packing the pannier bags.
Our last big trip together, Middelton 2013 we put the 3 pannier bags on the table, the first 3 items we each packed summed the process up and caused great

.
Mine.....tyre repair kit, first aid kit, wet weather stuff
Jean.....hair straightener, makeup case, then changed hair straightener for a bigger hair straightener cause it heats up faster than the smaller travel one....followed by a comment of I will leave my knickers at home before I remove the my hair straightener from my luggage

But we managed just fine.....2 people, 3 panniers and a Tankbag for 16 days travelling through and prepared for the high temps of the Hay plains and the lows of the Vic Highcountry......1 panniers sole purpose was bike related equipment and wets.
So with some fore thought and packing technics that will hopefully be discussed here......it is very possible to travel 2 up, light and in comfort.
Cheers
