Now thats a good place to be photographed! The bikes - thats the key. Will we get a bike that makes it through? I say a souped up Royal Enfield maybe the thunderbird for single riders and 500cc for riders with pillion. By souped up i mean -

upgraded (gas) suspension, disc brakes (front), heated hand grips (?), shock proof boxes and carrier for backpacks, provision to add a GPS on the dash board (next to the speedometers), Fog lights, upgrade 12V DC battery, Warmers (to keep the engines from getting cold at night), Tubeless tyres (boy what a difference this could make), strong clutch and brake cables, 45 litre fuel tank (or 22 liter but 45 is better).......

thats the bike part (with more to come) what else will we need? here goes..

GPS
GIS maps with elevation, route and climate details (?)
Solid gloves (to keep ur fringers from breaking off)
Digital Cameras with zoom
Laptop - to download the images

more as i figure them out.....
