op sec thoughts

[Midnitemo]

Was just wondering about op sec after an event...this is my issue , immediately after an event and for a little while after people willl still be cooking the remainder of there food supplies so cooking smells will be quite a common thing but as supplies begin to run out you run the risk of giving away the fact you still have food by the smell , my thoughts are after seven day's max i'm going to go on hard routine(no cooking)for at least the next three weeks,has anybody got any suggestions for hard tack bicuit type rations , looked at bp5(pricey)and liferaft hard tack(bit less pricey) any suggestions or thoughts?
