The old owner is notoriuos for being "a challenging individual" to work with. I fly out of there a lot and if I can't get back by 9PM, I have to go land elsewhere and get a rental car to get home. The runway lights go out at 9pm and they don't go back on until 6am. The owner will not provide after hours airport lighting anymore as he lives next to the runway and probably goes to bed at 9. I don't recommend landing there at night with no lights, the black hole approach is sketchy at best... I recommend KMJX Toms River as an alternative to KBLM. Last year the lights were kept on until 11pm from Memorial to Labor day, may be worth checking out. Good Luck.
