The gap itself is like the Vons Gap. The difference is that the 7-11 gap is highter and a bit shorter. When skating there, you have a good runway and landing but they are gnarly cause of the rough asphalt.
The 7-eleven gap is very fun to skate because you can hang out with your friends and sit on the curb. Then you can also get a nice refreshing slurpee after your tiring session.
