Yeah G.o.l.f.s.m.i.t.h. on Glenwood in Raleigh has an indoor court for demoing racquets, but I just show up sometimes and hit with a friend of mine. On weekdays they don't usually care.
However, they're closing our their tennis department. Court will be gone in May.
Looking for Sarasota-Bradenton hitting partners (4.0+). Message me through my profile. Get in where you fit in.
