There is no suitable alternative to the RSK for tarpaulin support.

Consider the options that a family can use to support a tarpaulin in a disaster situation.

*** NOTE: Only shelters using straight poles of wood or bamboo
that can be simply lashed together are considered here.
Shelters using curved or split bamboo are not included as
they require special skills and cannot be supplied as a kit.
