Like many arguments there is truth on both sides here. I love going to my LHS, and I'm lucky that there are still several to which I can go. Three of them are within a 30 minute drive and there's a fourth if I want to drive an hour. I love being able to walk through them and look at all they have to offer. There's an excitement to seeing all the variety, and that certainly provides an incentive to participate in this great hobby that a computer screen can never do.
BUT, that said like may hobbyists I have specific interests in what I build. (This IS the "Armor"ama site is it not?) When I want to build something I almost always have a SPECIFIC kit in mind, and with it will almost ALWAYS have a list of A/M items that I'll want or need to go with it. It is not realistic to expect that a LHS will have on its shelves EXACTLY the arcane items I want. Most shops simply cannot maintain that kind of inventory because there are not enough customers within DRIVE IN range to support it.
To support carrying enough inventory to provide everything that anybody could want, why you'd have to be able to have all the customers in the WORLD support your shop, and that's just not possible unless you had some sort of way to give all the customers in the world access to your shop............
Truth be told while I LOVE my LHS what I have found over the years is that nine times out of ten what I wind up buying from them is "commodities" like glue, paint, scratch building material, and tools. The more specific items I want are almost always something that so few people would want that I have to get them online. And yes there is a real benefit to be able to get in my car and know that within 30 minutes I'm going to have exactly what I want in my hands, but if it's a KIT, I've come to understand that there's a good chance my LHS will NOT have what I've decided to build.
It's the difference between going into a store and browsing and buying somewhat on impulse (what I call "shopping") or walking in with a fixed list in hand and walking out, (what I call "buying"). The LHS and the OLS cater to two different needs, and probably always will. As long as there ARE any LHS left.
BTW, @Pat, what stores in Detroit did Al Slisinger own? I've lived here for going on 40 years and I'll bet I've been in his shops at one time or another.
