You're not the only one confused about locations and their various names. I feel well-qualified to answer this; I'm a native Pennsylvanian (Altoona area) who just shakes his head when he sees something with just brief names or initials to refer to a locatioon here. To make things more confusing, some locations have a variety of informal and formal names for the same place or road. Well, here's the bottom line - hang on!
HOWEVER, the Boulevard actually extends from the very Southern part of Myrtle Beach to 82nd Avenue north. The best way to determine if an address is in the respective section is to look at the street address and MAKE SURE you know if the words include "north" or "south" - or just an "N" or "S". If it's LOWER than 3rd Avenue South -it's basically "South Myrtle"" (about half of the hotels/motels and some amusements along Ocean Blvd. are in this area.) If the address is between 3rd Ave South and 29th Ave North, it's "downtown" or the middle "main boulevard", "strip", also many hotels/motels, plus the Boardwalk, teen clubs, amusements, etc). The area north of 29th Ave. N. is hgher-end residential, with very nice hotels and resorts - often discussed in this Forum - around the 5000 to7500 block.
Looking at the bigger picture, many folks refer to "Myrtle Beach" as if it includes the ENTIRE Myrtle Beach "Grand Strand" region, rather than just the CITY of Myrtle Beach. Therefore, some people refer to the municipalities south of Myrtle Beach, such as Surfsice Beach, Garden City Beach, Murrells Inlet, etc as "South Myrtle." Additionally, people refer to places NORTH of the CITY of Myrtle Beach as "North Myrtle.,If someone mentions north Myrtle Beach, be sure to ask if they mean the "north end" of Myrtle Beach, or the City of North Myrtle Beach!
In between the CITY of MYRTLE BEACH and the City of NORTH MYRTLE BEACH are some areas such as "Restaurant Row" "Windy Hill" "Briarcliff Acres" etc. North Myrtle Beach, like most every other municipality, ALSO has an Ocean Boulevard and a Route 17 that uses "North" and "South" as part of the address. THEREFORE, you may see an address that merely says "2026 Rt 17N" - but you have to take note of the "N" for North. It could be BYPASS OR BUSINESS RT 17, and sometimes does not specify WHICH municipality; you have to find out if it may be Surfside Beach or North Myrtle Beach - the difference could be as mjuch as 30 miles apart. Some business, venue, attraction, etc. addresses in the phone book, an online search, or in brochures/literature are often listed as "NMB" - which means "North Myrtle Beach."I can't count the number of times I'm on or off duty where people pproached me and said they've been looking for quite some time (in MYRTLE BEACH) for some place that had no city listed and was actually in another municipality, or said just "NMB" and they didn't know that meant the city NORTH Myrtle Beach.. Overall, the biggest confusion is in incomplete or poorly-provided directions and addresses.
