As for replacing wood lanes with new wood, I doubt that you will see that happen. The price for wood lanes these days is higher than the cost of synthetics, unless a house can scrounge up some used wood lanes from a house that has closed down somewhere.
Speaking of good wood going to waste, a few years ago, the owner of the local center in town here gutted out a 24 lane house in Florida and brought all of the bowling equipment up here. He pulled out his old AMF machines and installed the Brunswick A2 pinsetters he acquired. He had 24 lanes worth of approaches, lanes, and pindecks sitting outside in the parking lot under a covering of clear Visiqueen. Well, clear Visiqueen will break down fairly rapidly under exposure to UV light, and it just so happens that sunlight contains a ton of UV during the summer months. About 3 months after he had piled up all of the wood on the parking lot, the Visiqueen gave up on the wood piles, and all of that maple and pine went to waste. He couldn't sell it for what he thought it was worth, so he buried it in a landfill. What a waste of good maple and pine. His reasoning was that the wood from the gutted house wasn't in any better condition than what he already had in the local house, so rather than switching out the lanes, he just did another resurfacing cut and let it ride. This year, he has since come in and put out synthetic lanes of some type, but I haven't found out exactly which type yet. But I do know that the new lanes didn't help the scores out in the house any. The new surface is some type of solid synthetic surface, since every individual board on every lane looks the same now.
