The "fine print". Thanks to HooligansX2 for the containers and to Michel-Angelo, Happyheartcacher, Chickymunkey, Blackspirit and NVATVC for the help in getting the caches out in the world! Please try to close up the caches to keep the logs dry. There is Wild Parsnip and Poison Ivy in the area, so please take appropriate precautions. No ticks were encountered while placing these caches, but you should still be vigilant. If there are problems with any cache, please message me directly, as I anticipate a very large number of logs for this Geo-Art.
