Hello List,
We have deep SNP test results returned for #62917. His tests show he is
Haplogroup J2f (in the FTDNA classification) or J2a1b (in the ISOGG
classification, which I will follow):
http://dgmweb.net/genealogy/DNA/Carrico/CarricoDNA-results.shtml#J2a1b
He had three positive tests, the first M304+ proving he is J, the second M172+
proving he is J2, and the third M67+ proving he is J2a1b (J2f). I've created a
SNP chart that will hopefully make it more intelligible how the SNP test results
are used to create a hierarchy of subclades and where we fit in:

We have one more member whose deep SNP tests are pending. He would be expected
to have exactly the same results.
As for what these results mean, well, that's what this research is all about,
trying to find SNP and STR mutations to define populations and lineages, then
describe how they migrated through time. You could say our genealogy is our
history, while our haplogroups are our paleoanthropology. There's an
interesting, if technical, article from the Journal of Human Genetics online:

If nothing else, do scroll down to the maps in Figure 2 and check out the one
labeled J-M67. That's us. Above the maps is a phylogeny with a (rough) time
scale that shows the M67 mutation appearing about ten or eleven thousand years
ago.
I ran a Google search on J2a1b, and I'm still reading about it...
