eeee! Martin, I never meant to imply that you were waffling! BTW, that second article is pretty interesting to me - IMO the MOD folks should have let the Mexican Government know they were going to have some folks playing around there.

The radioactives speculation seems to have originated with "local media" according to your article. What a surprise (not). Ummm... the best of the media folks I've dealt with over the years are fairly well grounded and willing to research what they don't know. Like any profession, the "best" are not representative of the "breed" in my experiences. Of course, the 5:00PM news reporter doesn't have the time to do much research before "reporting".

As for the rest of it - I barely know enough about anything to be mildy dangerous. Hence, "Is there a geologist in the house?"

The caving crew does seem to be well-provisioned - almost "professional", eh? Good for them. Thanks for the read - this is interesting.

Regards,

Tom
