Hi Billy,
You seem to have an issue with the size of your pics posted, they are either too big or too small; like in this case ;-). IOW, I'd like to see them in a bigger size if possible please. Do you live nearby this park? If so, you should definitely try sneaking in at dawn and/or dusk to get some more pictures. Lots of potential there.
Thanks for sharing.
Cheers,
Cem
