The large micro black cache is east of the bridge. The cache is not a tupperware container and does not have any letterbox stamps. Please return the cache to the same location out of plain view. Congrats to Madonne for the FTF.
Note: BYOP, carefully open the container/baggie, sign the log, completely seal baggie with log inside, tightly close container and replace cache out of plain view to same location in description/hint.
