You missed out Wes! I was in there for about 2 1/2 hours and I saw about 4 other people. Trail conditions were pretty much perfect
Also, It appears I haven't been in there in a while. I found a trail called "Instant gratification" that splits off from catalyst and goes to the doobatorium (somehow without crossing the river?) I think the trail that leads from the doobatorium up towards the chemical plant/science centre is gone now 'cause it looks like they're building something there. I didn't spend too much time looking for it though as that one is pretty tough and I figured it would be a very long, cold wait for someone to find my broken body.
The bridge under the train tracks at the top of the river trail is a nice addition too!
