So, on a rainy day, it is usually easy to just grab one of the sandwiches.
I was in the Arbroath cages yesterday, the Esbit stove worked well with RCIR main entrées, it was a bright sunny blue sky day.
Bridgford Sandwiches and some Chemical heater bags might be more useful when fishing on a more blustery Winters day when trying to reel in a Cod.
