Class time - I don't know about others, but Charles Cotton's class was entertaining, informative and "makeable" even though at the time I worked until 5:00PM in Galveston.
CHL bans in certain areas - CHL should be universal, but it's not. But you can still carry most places, except at my work.
Don't know how - Google "Texas CHL", you'll get many hits. Or ask on this forum.
