Meh, skip cabelas. Shits over priced unless you wanna see the bargain cave or just look around. I prefer GTdist over cabelas. Or even mcbrides with their high prices still have a good selection.
Wimberley- Leaning Pear. Or a little Italian place called Marco's, but look them up because they have weird hours. Guy basically hand makes everything to order and it is a very small place. Mima's has good breakfast tacos and sauces, cash only. Middleton brewery really didn't impress me with their craft beer. Wimberley Valley winery for some local wines (sweet) and a shaded tree to drink under. Creekside Cookers is a food truck, that is decent bbq. Not excellent, but pretty decent and you get a lot for your money. They do sell out fast though and close when they sell out.
Dripping- don't know much. Nutty Brown amphitheater had some good beer choices, last time I was there about 4 years ago.
Fredericksburg- there was a neat gun shop in the shopping district off the main street. Not much selection, but was a nice get away from all the girly shops.
Google gun shops near me when you get there and it should pop up.
