I love Excel. I don't do a ton of complex stuff with, but one of the most useful things I've done recently: We were trying to build out three fairly large raised garden/flower beds. After a couple times of doing everything by hand, did a little quick Excel work that would take my desired width, length, and depth of the beds and calculate volume, number of 16-foot boards I'd need, number of bags of dirt I'd need, and how many stones I'd need, then price it all out, add tax and shipping, and done. So I could easily compare 3x10x1 beds vs. 4x10x.5 or whatever. Came in very handy.

Honestly thought concatenate was a typo. Thanks, Google!

You know Marty too?

(I'm gonna be a little creeped out if your answer is yes.)

LMAO
Yup. Marty F.

Nice. He and I used to shoot together back in the early 2000s. Small world and all.

It sure is.
He and I worked together for a few months on some projects before he went to work for big "G".
