Also, if you're an AHA member, you should already have the Brew Guru app on your phone. No, it doesn't provide a lot of feedback on each place, but it is absolutely one of the best apps I have used. Read Tim's guide and then use the app to see where everything is and to get AHA discounts at many of those locations, including push notifications that you're near a business offering a discount. If you're a homebrewer and not an AHA member, you should be. Regardless, you can download Brew Guru and get a 3 week trial, or still use the app for free as a non-member, just w/o the discounts.
The AHA discount, especially with the help of Brew Guru, has more than paid for my membership. No, I don't receive any compensation from the AHA - just a happy customer.
