Cavers, The Bexar Grotto is searching for several sets of lost survey instruments (Suuntos or equivalent). They may have gone missing as long as 5 years ago or more, so if it's possible that you borrowed a set from the grotto some time in the past, please check to see if you may still inadvertently have them. The Bexar Grotto name should be inscribed on the instrument. If you know where these instruments are please reply. Thank you, Marvin Miller
