Is it wheelchair accessible?

The store has a side walk and the area around the field is pretty flat, but the fields aren't accessible.

This year, visitors can park on both sides of the field, and, while the sunflowers generally grow too close together to get a wheelchair through, there is an open lane between the corn field and the sunflowers that could be traversed by a wheelchair or motorized scooter. I have some problems walking, so took that lane to walk down along the sunflowers, and the field is pretty flat this year.
