Here's the best source I have for used bowling lanes.

Fun material to work with. As has been said, nailed not glued. In my experience, the nailing is confined to the lower 1" or so of the planks, which are usually at least 2 1/4" thick or more. When I need to remove the nails, what I do is place the lane down on the floor and put 4x4" blocking under one long edge. Walk down the middle and it flexes like a stiff tambour door. At this point careful prying and hammer application gets the boards separated from each other. Once the boards are separated it's easy enough to remove the nails with a nail kicker(punch nailer) and a set of dull nippers or something like the crescent nail puller pliers.
If you've never heard of a nail kicker, it's essentially an air nailer without a magazine and a tube the drive pin rides in. I'm familiar with two manufacturers, the original Nail Kicker made by reconnx, and a value brand version made by Air Locker. Kind of surprised I haven't seen one at Harbor Freight yet, considering the Air Locker body is the same as HF's Central Pneumatic crown stapler. Which one is for you depends on your use. The AL only comes in one size, is non-adjustable and has no built in safety. The NK has a press safety, drive pin and nose sets are available in 4 different sizes, and it has a depth of drive setting feature. $55 and $350 respectively for the AL and NK. I like and own both versions. The AL size is approximately the same as NK's V20-40, their smallest size.
I do find that the NK is worlds better when working from the front of the board and driving through. The AL version doesn't extend the drive pin much more than 1/4" past the tip, whereas the NK can be set for .1", .41", .87" and drive sets can be custom ordered with more than an inch of travel. To use an example, deconstructing pallets is a very common task for both of these units. With the AL, I find the best approach is to pry the pallets apart and then kick the nails out of the boards. With the NK, you can set the depth of drive to it's maximum and the kicker will push the nail head and all through the planking. This does render the stringers less useful, as they become full of nails. Nobody I know that reclaims pallets uses the stringers for anything but firewood, so it's a moot point to me.
