Date tonight flaked, and then five minutes later a pigeon shat on me. :lol *Now* I'm experiencing the real Paris!
I may have missed out a bit out here since I have been away for a while, but being as you are in Paris (and just after August which is a bit of a dodgy time).
DO the Sunday morning skating by the river
DO NOT DO the Rue St Denis at any time unless blindfolded
DO contact the Baron Lundi, who has good taste in things Parisian (or at least much the same taste as I have).
DO NOT DO the Jardin des Plantes, it is woefully neglected these days, no matter what the historical/scientific interest.
DO follow the policemen on rollerblades - they are usually chasing something of interest.
DO NOT DO even-numbered arrondissements.
DO hang around the Marais at night and see what happens.
DO NOT DO the top end of the Champs Elysees (unless you are sitting on top of the Arc de Triomphe dangling your legs over the side and HIGH).
DO get freebies at the markets on and just off the Rue Mouffetard.
etc etc.
... plus, of course ...
have a hell of a lot of fun there. My favourite city by far.
Also, there used to be an awesome place for Ice-cream on the north side of the Ile-St-Louis (just past the bar where I did the washing-up to earn the money for the ice-cream). Don't know if it is still there.
