If the releaser maxed me out at 24", I'd buy a new releaser...5% more sap for every 1" above 20". The new releaser would be paid for pretty quick in additional sap.

Surprisingly, we picked up another 320 gal today off the vac. woods. They must start picking up steam around noon time because I'll check the tank at 7am and there isn't much sap collected between then and when my wife stops by at noon, but by late afternoon when it's picked up, we'll get a decent run out of it. SSC is still at 1.4% and the RO's working on bringing it up to 8%+ for me. I'll boil for an hour again tonight and I'll make another 4 gal or so. Based on what I've seen this week, we'll be able to get through this weekend, but I wouldn't expect much longer than that.
