I'm having problems with a migration after cleaning up an oddity with a
date field and I'm not sure how to fix it.  Any advice appreciated.

I made this change to a date field:

-    start_date = models.DateField(db_index=True, default=False,
-                                  help_text="The date enrollment can begin
this Season.")
+    start_date = models.DateField(db_index=True, help_text="The date
enrollment can begin this Season.")

I'm not sure how a default of False ever made it, but I ran across it and
fixed it.

This is the migration that was created:

class Migration(migrations.Migration):

    dependencies = [
        ('district', '0012_auto_20160622_1741'),
    ]

    operations = [
        migrations.AlterField(
            model_name='season',
            name='start_date',
            field=models.DateField(help_text=b'The date enrollment can
begin this Season.', db_index=True),
        ),
    ]

This is the error I get trying to run the migration:
