Take a short drive 2-3 hour drive on I-80 west to Omaha. Spend the weekend there.
There are 3 LHBS's in Omaha (maybe one reason we were were listed as a top 10 drunkest city in the country a couple years back) They are: Patriot Homebrew Supply, Cornhusker Beverage and Fermenters Supply.
While all have most things you might need, I highly recommend Patriot Homebrew supply on north 204th street in the western suburb of Elkhorn. They are heads and tails above the rest. Their selection and service are the best. In fact, they were voted one of the top 4 Local homebrew stores in the country at last year's Homebrewcon.
Their grain selection is great and they sell it by the ounce, lb or bag (mill it onsite yourself if you want). They also have a good selection of hops, yeasts and Brewers Best extract kits.
From an equipment standpoint they have pretty much everything you might have seen online available for sale including kettles, kegs, bottles, parts and pieces. Their prices are competitive. They also sell winemaking supplies. If you are needing something specific, you can facebook message them.
They are open weekdays (except Monday) 11-6:30, Saturday 10-3, Sunday 10-1.
