@pixychick , I'll just offer my opinion for what is worth if you don't mind.
I live in Ringwood and while not enough skilled to take full advantage of the trail system here, I can still appreciate the effort that has gone, is going and needs to go into keeping these trail available to the riders.
At first I joined JORBA because I believe that was a way to chip in the maintenance of the trails that I would hopefully ride and enjoy in a few months, but I do understand that can't be nearly enough. So volunteering was the next step. I did a couple of dates for NICA just to find out that one of them was in coincidence with a TM at Ringwood (it would have saved me an hour drive to 6MR on top of the fact that I was gutted for not being able to attend the TM in the town I call home, but I don't commit to things and then back off a commitment unless there's a major reason for it). So you got a point there, based on my direct experience, even though I don't regret for a second helping out getting young kids interested in this sport, NICA seems to be taking from TM time.
That said, from the point of view of an OOS (literally and figuratively, I've got the shirt and the girth to prove it), I believe the key to have more TM volunteer would be to advertise them in a more pressing manner (as mentioned by
@pooriggy,
@Norm joyfully pushed everybody to volunteer at NICA and I am glad he did) and possibly have more of them during the weekends. In my specific case the second is key.
Reading everyone's riding adventures on the MTBNJ.COM website I can't help to envy the time and dedication that goes into riding, but at the same time I keep asking myself...is anybody working during the week here in NJ? I personally leave home at 6:30 am and limp my buttered ego back around 8:00 pm every day, spend little time with my better half (who's not a rider unfortunately) and then go to bed ready for next round the next morning. I would gladly put some of the weekend time (especially in the morning) toward some track maintenance in Ringwood, and I'm hoping to be at Sheperd's Lake (or is it pond?) on 7/20 for the extra TM day you scheduled, but I can't put in time I don't have during the week. Unfortunately, I don't see the average Joe taking a day off to do TM.
Sorry for the long post, and thanks for the time and work you guys put in the trails.
