Organized, vast and reasonably-priced assortment of rocks, minerals, jewelry and fossils.
Burnie's is a modest-sized store located a 1/2 mile or so from downtown. Within this shop, they include as much per square foot as I have seen in like establishments (white space be damned).
Rock enthusiasts love their selection. Their prices are on par with larger shops and Burnie's includes more higher quality selections.
My child was excited by the dinosaur fossils and the learning kits ($2.50 kits explaining and tying together minerals, rocks fossils and ore with real materials).
The only thing missing was the ability to mine for gemstones via the five-gallon bucket. Of course, lack of space prohibits it, but to engage non-rock enthusiast ... hands-on activity is important.
Regardless, its nearly perfect for anyone that would seek it out in the 1st place. More space could add to more fun ... but it would likely be at the expense of its convenient location.
