Sour? How about Sour from TPA/TFA? I think Loranns makes a Sour too. I know they are better at adding sour than lemon
juice because lemon
juice don't add a sour note.
Must haves for a Newbie? Um, a good attitude and a willingness to make notes is better than all the equipment and bottles of stuff in the world.
As for vapor shops in Indiana, I know most of them. Due to my involvement on the Hoosier Vapers club council, I'm not able to recommend any shop over another as one of our missions is to promote all B&M shops in the state. I can say the guys behind Cravin' Vapes are good people and have been supportive of the club.
Also, if you live 2 hours south of Fort Wayne, then maybe you might want to stop by the Silver Bullet in Beech Grove from 4-8pm on any third Saturday of the month to get "unfiltered" opinions on shops and such from fellow vapers? Many of the folks who attend are not shy about sharing opinions... (And I get a kick out of AG and Jay debating the various merits of various
mods.)
