Every day I go to work, this bag goes with me. If I go away from town somewhere, this bag goes with me in the car. I don't travel by plane anymore, so I have no concerns about security checkpoints at airports. Some of the places I travel are a little on the remote side. This is also a work in progress.
Anyway, on with the show. Here's my bag, a High Sierra.
In a side pocket, I keep an LED head lamp and an LED torch.
In the smaller of the two main compartments, I have another LED torch, some Reg Grundies & socks, a container for my GPS unit (Bitchin' Betty (Tom Tom unit) is currently in the car) and a box with some bandaids, cold & flu tablets and pain killers.
In the larger compartment, I have a 10' x 8' plastic tarp, 30 metres of 6mm poly rope, a couple of litre water containers, my first aid kit, another LED torch, and another container with some bits and pieces.
I also carry the baby wipes and the fire kit in yet another compartment, along with another LED torch.
In my car, I have about another 3 torches, another first aid kit, another tarp, about 100m of rope, another fire kit, some cash, a blanket, an umbrella, a cold-weather parka and a sloppy joe.
Car care wise, there's a tool kit, 5 litres of engine oil and 5 litres of engine coolant, as well as a funnel and a rag.
