I know that tuperware containers aren't the worlds most expensive item, even ammo boxes only cost 4-5 pounds but . . . .
There are some places that have a ready supply of FREE containers that we (as cachers) would find very useful.
For example, a friend of mine works for Thames Water, they use a growth medium for sample cultures. This comes in large screwtop barrels (10-12 inches high by 7-8 inches dia) with 'o' ring seals. They get through about 2-3 a week and when finished they throw the containers away !
My friend has saved me two of these and they will make great caches. Look here - BC2 - Walking in Circles - for one already 'in the field.'
In the past I have worked at an RAF base where aerial photography took place, they had a ready supply of large (8 inch dia, 8 inch high) plastic film canisters which they regularly dumped.
Does anyone else have a good supply of free containers ??
Or, can anyone think of somewhere suitable containers could be gathered from ??
