spelunking

i kinda want to do this.
anyone interested?
not sure about the cost other than the $5 rental.
seems like guided tours go for about $50.

and why does it seem like there's a crapload of caves in BC, but only 3 in Washington?
although i guess most are in the northern part of Vancouver Island.
...probably a combination of the fact that there's limestone rock and uplifting due to Juan de Fuca's subductionwhich creates underwater rivers and hence these caves.
