There's always someone making nasty with the HL thing.
Now this is a Hlocation in in Unlikely Place Believe it or not, there are actually a few places in the USA that start with HL. Well, actually, two. But two is something, isn't it?
1..The HL place name in Alaska Feature Name: Hlukkuhoan Feature Type: locale Description: in SE Alaska. History Notes: Former Tlingit Indian town listed in Hodge (1907, p. 554)
Apparently this is translated somewhat as "Hlaxq! uxo-an" in Tlingit, meaning: "town where people do not sleep much." Probably because we're being bothered by people who don't understand HL.
2. The HL place name in Texas Feature Name: Hlavacek Lake Dam Feature Type: dam State: Texas County: Milam USGS 7.5' x 7.5' Map: Pettibone
