Here is a list of which member groups have hosted or co-hosted a VAR gathering since1975. With 44 member organizations, every group only needs to host once every 21 years if all take turns, but some grottoes host a lot, and others very litte. If your group has not hosted in a while, please consider hosting or co-hosting a VAR!
