Slackline for beginners at Phoenix Park

Meetup will take place in the forest near Wellington Monument between the road and sports ground. I've marked exact location on the map - http://goo.gl/maps/wa5Xj

There are plenty of reasonably sized trees, and afternoon sun tends to shine through them. I've also marked down secondary sheltered slackline spot, in the unlikely case of rain.

Q&A

Q: What to wear for the Slackline meetup.
A: Best outfit is outdoorsy and loose pants, warm layered top and shoes with thin sole. I personally wear Vibram fivefingers when walking the line, but if it's warm enough I prefer to do it barefoot.
