Horses and dogs defecate here constantly and there's virtually no enforcement of policies to prevent this from getting worse (at least with the dogs). Often there's drunken people here on Sundays, and they're not exactly "from the area". They then meander up the trail to the smallest hill in their street casual clothes, laughing, and not watching their wandering kids.
Weekends are horrible here because everyone finds the need to say hi to every single person they see going the other direction on the path. It gets old, people. So, avoid weekends if possible.
Trails were much better before they made so-called "improvements" in the way of widenening the paths. Now there's an oversupply of overzealous mountain bikers who don't know that pedestrians have right of way, and are so lacking in dexterity that they can't seem to slow the bike without skidding down the hills.
During prime weather months it is common to have a local pastor sing religious songs on top of the lowest mountain, with a guitar. I'm not sure if I'm more bothered by the fact that he does this, or by the fact that other people are not bothered by this as much as I am.
