I've calmed down enough to write this now.
If anyone knows Follow Me at Lysterfield they'll get this.
Basically for those who don't, it's a fun, mildly gravity fed one way trail with LOADS of trees everywhere either side of the trail. It's not wide, there's precious little run off and only a sniff at "b" lines. Basically it's got speed if you want it, but if you come off you're hitting a tree most likely.
I'm hooking along and on one of the doubles my foot unclips mid air. I land it after getting it back in and pat myself in the back. Decide to stop, get well off the trail and compose myself as I was probably doing about 35km/h (who knows..)
I'm about to get back on the bike to ride down the rest of it after having checked the direction I had come from, clip one foot in and set off to find a guy pedalling UP the trail, the wrong way cheerily asking "Is this the way to the start of Follow Me?"
It took every ounce of restraint not to choke the life out of him and ditch the body in the lake.
A few choice words explained how lucky he was I'd stopped as we'd both be in hospital.
Morons... they're just everywhere and you can scarcely avoid them.
