You get used to the mesas and canyons, the only real issue the canyons and mesas cause is that there may only be one road to access some area... and it may not be a bike friendly road.

But the So Cal car culture is pretty strong and motorists love to drive fast around here... sometimes you want to just brain the motorists that don't even bother to look.

Some of the newer areas of town have nice wide BL and are fairly well connected. MUPs tend to be isolated and somewhat incomplete... kinda almost getting you "somewhere."

The thing that really is nice is the weather... year round biking in little rain, and no snow... really this place should be biking heaven... except "nobody walks in LA..." the drivers can be hell on wheels.
