In my own personal opinion:

BMX and or skateboarding = Writing/producing original music

Powerwalking = Producing covers

Rollerblading = Making edits or mash ups

Segway = Blogging
so yeah, i'm guilty too, (but give me a segway and i'll at least try to jump ramps on it).
these are just thoughts as me and some friends paroose the ttl blog and say: "the lab blog overall needs to step it up"
