I finished my meeting and got to Trumbull at about 4ish. This place is a LOT of fun. It's not so big so I don't think you'd get your distance-fix here but the rocks are great to play around on.
I headed in on the red trail until I lost it. Then tooled around on the yellow trail making my way as far noth as I could. I came across a dog park and a playground area on the east side of the park too.
When I thought I'd reached most northerly tip I followed the river down to find the blue trail and hurtled along that.
There are loads of criss-cross trails too and I didn't take them all. The trails take good advantage of the rocks and you come across loads of 1, 2, and 3 foot natural jumps. I took some pcis with my phone. They're a bit fuzzy but you get a tiny bit of an impression for what the place has.
A common rock jump, with my bike for perspective:
This roll-down on the red trail is pretty steep, although you can't tell from this angle;
Here's the view looking down it:
A nice, big log roller:
You can give this a go if you like. The height in the centre is about 4ft:
And then work your way up to this drop:
As I was getting changed at the end I got chatting with a guy who was just about to head out. He had a Gary Fisher 29er and was wearing the kit so I asked him if he knew Jimmy Vreeland. I mentioned that Jim was just at Allumuchy and races for GF throughou the summer. It clicked and he says "hello Jim!". His name was Micheal and he's based in CT somewhere.
