MD: MD 135 Point Concerns

[Markkos1992]

1.  Maybe add a point here as this road is signed as an access to US 220.

2.  From what I have seen, MD937 here is a secret designation so the label should be MainSt.  I might try to clarify whether MD 937 is signed this weekend if I do not end up doing my Eastern Shore almost DE clinching.

3.  I also recommend looking deeper into what is up with the Camp4Rd label.  It is in the wrong location according to the HERE Maps, but OSM and Google seem to pretend that it does not exist.

(On a side note, duke87, I was looking for a response from you in this thread (https://forum.travelmapping.net/index.php?topic=4760.msg26644#msg26644).)
