It's that time of year.

Pre-ordered boxes of Girl Scout cookies are being picked up and deliver by Girl Scouts in the Pikes Peak region.

Booth sales start Friday.

Girl Scouts began selling cookies in 1917, according to their website, and today the program has grown into a $790 million girl-led business.

In Colorado in 2012, Girl Scouts earned $2.25 million for their activities, such as going to camp.

This year's cookie variety includes Do-si-Dos, Samoas, Savannah Smiles, Tagalongs, Thin Mints and Trefoils.
