I found the drain holes, thank you. They had some dirt in them but water seems to be draining fine. Also, since the tube doesn't run through the trunk area is it even possible clogged drains would cause water in the boot?
I know another possibility is the tail light seals leaking.. i posted on a separate thread about that. Looking at the tail lights though I don't really get how water from the tail light could get in the boot
Not really sure how to figure out where the water is coming from other then doing a garden hose test I guess.
