Since I am in Arlington, I tend to stick to the trails out here, and overall I can't complain. I am usually out there during the week so there aren't any crowds to compete with and I can get in a nice twenty or thirty mile ride at my leisure. Lately I have been seeing a grey and white bobcat or wildcat (depending on where you grew up) wandering on the trail. Yesterday he came up pretty close to me, eight or so feet. I wasn't scared so much as I was worried, as it was pretty far out into the woods and I had passed a couple of mothers with small children.
 
Wondering what the etiquette is in this situation? Do I warn others that there is a big cat wandering about, or is that assumed when you're in a nature preserve you're going to see that type of wildlife? I don't want to freak anyone out unnecessarily if I don't need to.
 

A couple of years ago, saw a sandy-colored bobcat on the White Rock Creek Trail in Valley View Park with a squirrel in its mouth. At first, thought it was a dog, because it was so big. It ran down into the creek bed, as I approached it.
 
Ran across a large rooster in the woods, last Sunday afternoon, as I was riding the trail extension, North of Valley View Park. A bobcat or coyote probably had nice chicken dinner that night.

Off topic a bit.
 
I was unaware of this trail and am now curious as we have family down there and I may want to ride it.  Appears as if you can start on the south end at Dotty Lynn and ride it north east to 360.  Is it all paved, conducive to a trike and wide enough to actually enjoy?  How long is it from end to end?

Sounds interesting, thank you.

I know this is an old(ish) thread, but my wife and I just rode the River Legacy trail and saw the bobcat mentioned earlier.  It did exactly as others have said, moved off the trail as we approached then back on after we went by.  
 
It was our first time on the trail east of 157 (Collins).  We parked in the lot on the west side of 157 and north of Green Oaks.   We first rode westbound but the trail was fairly crowded with walkers and joggers, too curvy in places, and is still under construction in a few places, forcing you to get off and walk your bike unless it has wider tires or three wheels.  Not fun.
 
Then, we crossed under 157 and headed east.  The difference compared with the west side was dramatic.  Because there is only one entrance to the trail east of 157, it's not very crowded and nearly all bicycles.  Mostly wooded, occasional open views of the Trinity River valley, fairly new concrete, not too curvy, and nice and wide.  It's so nice that it just might be my new favorite trail in the metroplex.
 
My wife was on her road bike and I was on my Ti Aero.  We saw another guy on a Bacchetta and someone on a trike.  Not sure what brand or model. Highly recommend trying out the trail if you haven't already.  Enjoy!
