Myrtle Beach is OFF the list but you really should not write off the area... Stay outta MB of course but the grand strand and Murrells Inlet are VERY biker friendly. Suck Bang Blow (sorry moderators, that is the name of the place. SBB in the future) is the biker bar of biker bars and a great place to hang out. The area is great as long as you stick to the grand strand and dont go into MB. A friend of mine is one of the owners of SBB and tells he is part of a business development association to attract and keep bikers, they did a patriotic rally last year and there are plans to do it again.
Dont write off the area just the MB pinheads...
