Our local Homebase seems to have a lot of Calorlite, can they be utilized somehow??I am concerned about the shortage of gas. We are planning a 2-month trip and so-far have only been able to collect 1 x 13 kg of gas. If it becomes as difficult in Europe as it is in UK right now, we are hoping to use campsites more and cook using our microwave. Not really looking forward to that and have picked up a few single-use bbqs. What contingency plans do you all have and how will you guys manage cooking microwave or bbq only?
