I bought a 'match trolley' , a 'carp umbrella' and some ordnance survey maps of Islay today at a local fishing emporium. Fishing shops are great when looking for equipment for going portable, as comfort and rain proof are high on the design criterion of most of the products, and that's exactly what's needed here in GM for portable work.
I'll need the trolley as I don't want to be limited to operation from the car and the 110A/H leisure cell I'm taking weighs enough to give me a hernia. The trolley has big puenumatic tyres on it to soak up any rough terrain and as an added bonus it will also double up as a rather comfortable chair.
The reason for the umbrella instead of a tent is to get round any objections to 'camping'. With the umbrella I can sit down and operate in any remote spot without any possible land owner getting worried about it turning into a camp site. The umbrella is huge at 2.5M in diameter and has an extendable pole with a spike on the end for ground mounting. There is also a guying point on the apex if the wind gets up. I should be able to sit under it on the trolley with the laptop on my lap and the rig beside me. Imagine a fisherman on a riverbank and substitute an antenna for the rod, a K2 for the tackle box and a laptop and logging software for the keep net. I'll even be wearing wellies for goodness sake! They can sit there for hours in comfort so I'm gambling I'll be able to do the same.
My only worry now is the Midge. Midges are a small biting insect which we have in GM (especially the west coast where I'm headed) which can drive you a man to insanity, a cloud of the little blighters can decend on you and all you can do is run for cover. The fishing shop had some mosquito nets, but the mesh was really too large to deter them. I'll maybe have to make do with a midge hat and repellant.
I hope that a better solution will present itself when I arrive on the island, but I think it's always better to prepare for the worst.
