The skies of VT and NH are incredibly empty.

Except near the airports where the newbie pilots are concentrated. (My original point.) Though the worse case is 3-4 trainers in the air, a towplane, and 3 XC launching at 1 pm.

Sometimes I think that in this neighborhood a Trig Mode-S transponder would be more valuable than a PowerFlarm as both Springfield and Sugarbush are right on Victor Airways to Burlington and Lebanon. 4-5 biz jets not uncommonly land at VSF on Saturday afternoon. TCAS is a beautiful thing.

The PCAS function (transponder in the neighborhood) of PFlarm is valuable for GA traffic (as Tony mentioned).
