I travel a lot, and if I have any spare time, I like to look up model shops on Google Maps, call the shops to see if they're open, and go visit. Given how volatile the world of retail has been for the past decade, you never know until you talk to a store employee if a Google Maps listing is current and the shop is still open. (Back in the day, before Google Maps hit its stride in terms of place listings, the back pages of FSM used to be my source for hunting down shops.)
It seems that most hobby shops these days cater to RC (which is fine by me, because I'm also an RC enthusiast), but I still love browsing through rows and rows of plastic models.
On a trip to Portland, OR earlier this year, I was happily surprised to find a handful of shops that were within 20 minutes driving distance of downtown, including Bridgetowne Hobbies. Unfortunately, soon after I made my visit to Bridgetowne (and purchased a few things), the store closed.
Last year, I was motorcycling my way up through CT, and I dropped into Time Machine Hobby just east of Hartford. Wow — what a place! Luckily, I had enough room in my top case to fit a few models and other toys.
In Pensacola, the LHS count is quite high (understandable since there's a big military population there), and even the local Hobbytown stocks a decent selection of models. Bobe's in Pensacola impressed me even more — a great store worth visiting if you happen to be in town.
Like Pensacola, the DC metro area seems to have a healthy number of shops — although none of them really stood out to me enough that I felt I needed to make a second visit.
And if I'm anywhere near Marlborough, Massachusetts, I try to make my way to Spare Time Shop. The store has rows of model kits, floor to ceiling, including many vintage and hard-to-find kits, even in this age of being able to find things so quickly online.
Anyway — with all that said, I'm not sure if there's truly been a hobby shop revival, or if it's just that Google Maps (and other online resources) have made it easier to find open hobby shops.
