southside is an indoor skatepark in south houston/pasadena area, they have a sweet shop inside, kinda looks like SPOT and they have been featured in some of the skate dvds. They recently got the sb account right around the same time as source board shop,im certain they are affiliated.
^ ya, they are the same business, just diff locations. If I recall correctly, they actually have the SB account at Southside, but they used to bring them all to their Rice Village location because they wouldn't move them at Southside. I believe now they are buying size runs from Nike for both stores - thus allowing them to technically have twice as many as most individual SB accounts would have. Assuming they would take all of a particular SB to the Source location.
