This should be a quick find, there is plenty of parking in the church parking lot. I have never seen it more than half full even on Sunday mornings. It will be a short hike into the wooded area and there may be standing water if it has recently rained.
You are looking for a camoed "Berty Tube", a container given to me from a infamous Houston Cacher- Baytown Bert (about the size of a soda tube).
Congratulations to PROBOB and Dave & Mary for the Co-FTF! .
