Hi All I'm looking for a recommendation for a tarp or similar item I can use as an occasional shelter for bad weather, stopping for lunch etc. rather than for hammocking or bivying under. It will be used by two people maximum, we'll usually have walking poles for roof supports and probably have a couple of tent pegs for the bottom etc. How big a tarp are we likely to need? Anything else worth taking to make it more usable / practical? We're off to the lakes soon and I want to make stops a little more comfortable as well as emergency shelter if the wind & rain really starts. Realtively small and light is preferable as it'll be in my pack on days out.
