We did a couple of years ago. Nice facility and not as large of crowds. Fun time, i think we opted for the ride around the farm after and played frisbee on their big lawn. Grab a bag of pecans as well.
If i remeber they did either a slight stagger for younger kids or roped off different areas. Just watch for a poison ivy area to the far right if memory serves
Another one we like and went to yesterday is Antique Rose Emporioum on way to Brenham. They are having another one today as well
Nice place to walk around and we have kid pictures under same tree area for almost a decade it seems.
And a stop to Truth BBQ in Brenham for lunch yesterday was awesome
