I've sent the post cards (SCGR), sent the e-mails, made calls, talked with pastors and deacons, presented a resolution at the precinct meeting and will be very disappointed if S. 261 does not go thru.
One thing which needs to be done yet, is put pressure on the NRA to put their money and backing where their mouth is (or isn't). Last time I communicated with the NRA-ILA, a Mr. John Shipper was the SC state laison. He can be reached (last time I tried) at 800-392-8683.
