The new transformer is working great and we've moved our Sunday hours back to opening up at 9am.
While we were waiting through rain delay after rain delay for the new transformer (which is not a complaint because we need and appreciate the rain!), we had to use the interim generator. Thus, we had delayed opening up until 10am on Sundays to let our neighbors sleep in.
With the new transformer in place, we're now back to opening up at 9am on Sundays.
