Go to the end of the road at Linwood. Or go to Pinconning Park. Three dollars daily fee but before sunrise you probably won't be asked.
Gates open at 8AM. Though it is illegal to be in the park before then, if you're there just to watch the sunrise, you'll be ok. But with the gate locked, you won't be able to drive in and parking along the road is illegsl.
