Packing or squeezing?

As a group of 10 DIT student volunteers, 2 DIT student Interns, 1 Volunteer Design Engineer and 2 Old People we will take 30 bags each stuffed to the last gram.
This may or may not be the last items and who knows where a tiny space might appear.
We will also bring 7 Kg each of hand luggage plus a laptop and bag plus a small camera plus reading material for the 36 hour journey to Mzuzu..
This year all are novices except three!
This stuff contains a cross cut chopsaw from My-Tools.ie in Tipperary accompanied by a multinational array of soft toys.
Two grinding stones donated by Ken Dunne, Sureweld, Lucan. A load of seed donated by MG Seed Company in Ratoath, Co Meath, ten sawblades and a bathroom scales to keep a little control.
