Thanks for asking JNI64. Unlike Goldenbear, I haven't been keeping track until more recently so I'm only at 8 (mostly in the mid-atlantic and northeast) but I'm planning a camper van trip down to visit some family in the southeast this February and so I should be able to knock off quite a few more. Also in 2023 I hope to hike the AT. If all goes perfectly I could end up with 21 forests visited by the end of 2023! Then I'll be off to explore the forests out west in 2024.
