I've spent the last few weeks talking and texting family members. Here's what I've gathered about who attending so far.
Three of my step bros except one of them isn't bring his kids because his wife is concerned they will be confused. One of my blood bros is coming but the other is on the fence. He said he thinks they will be on vacation that weekend (wink wink). All 3 of my blood sisters are not coming. One lives in south America, the other lives out of state and is legitimately busy, and the third is a Jesus freak. Woof
