if we come well before 8pm July 4th 2021, can we bring in a lawn chair? 3 hours is a long time to be standing around.

yes you can

By 6pm there was nowhere to place a chair. I was there since 3pm. Glad I did because by that time everyone was like sardines

Yes

It had to be before 6 PM

As far as I you can however their no need to,

Chairs *may* be allowed but there are no guarantees. Unsure if updated rules may now prohibit them. Blankets are more preferable.

Yes plenty of space hopefully it won't be too crowded though
