When is it the best time for Parkour?  Is it an all year round thing?  Im just wondering because currently me and a friend of mine are really into this, but we have absolutly nowhere to train, not to mention that is snowing outside at the moment.  Should we train outside only on warm days or will it not matter?  We want to get some indoor time, but we have no idea where we could have the same obsticles (not to mention pads to fall on) that we find outside. Any suggestions?
please and thank-you!
 

The point of pk is to be able to get somewhere as fast as you can in any situation (even if that somewhere is anywhere but here). So, being able to pk in all temperatures and weather would be a good idea (that is why i don't really like the idea of being a FWT). I'm not saying go outside and pk on a roof with snow and ice, i am just saying don't restrict yourself to only one kind of weather.

Think of the weather as an obstacle, just like a wall or a bench. It might not be tangible but it is there, and in any situation it is something that needs to be overcome.
