I'm in the same situation as you - I live north of Indy and my woods is near Bloomington. I've held off tapping because I don't want just a little bit of sap to sit in my 250 gallon collection tanks [3/16 lines running to them] for too long. My thought was to wait for when things were really running, but please let me know how yours do over the next few weeks - maybe I'll jump in a little earlier!
2014 - 8 taps, turkey fryer, 130 gallons sap, just under 2.5 gallons syrup.
2015 - 50 taps and counting.
2016 - 60 taps on 3/16 and a Bill Mason evaporator on order.
2017 - 115 taps on 3/16, homemade r/o.
2018 - 150 taps on 3/16, r/o a big help, but lots of leaks killing yield.
2019 - sticking with 150 taps or maybe less, focusing on good vacuum and less waste to increase yield. Doubling up my r/o, and made a vacuum filter that looks promising.
