People tend to check in during these times:
Beautiful Scenery at sunset. Fun place to bike or jog
It seems like this park is almost always empty. Not necessarily complaining...
Fireworks are here for the 4th
Bring your hat, parasol or plan to stand in the shade .... not much shade on battle field. Check out the doctor tents.
The city really needs to fix the trail, it has many flooded areas since they paved it.
