btw -- speaking from very recent experience... if you do the loop from the golf course around the back of Plaza Holanda, take care when you're coming around the turn on the Figueroa Alcorta side! There's a point where the bicisendra gets narrow and on one side there's a metal barrier for the road, and the other the wall of the train bridge overhead... I lost control there yesterday when my chain jammed and stupidly I looked down to see what was happening instead of looking forward and ended up taking a nice gouge out of my shin on the barrier -- in the end had 10 stitches, a tetanus shot, 48 hours of antibiotics, and a 4 hr wait at the guardia... make sure to bring your prepago card with you if you're out on your own, lol!
