Read Thread: St. Louis Gather in January
Bring your biggest boots and thickest coat, and maybe that will guarantee balmy, 50 degree weather!
Of course my thickest coat is in CT..... I had a thinner coat in Maine last January and did ok.
If you want to find great boxes in those 3 states, you would be advised to shoot over to the Evansville, IN area and find boxes there and in the adjoining states nearby. The letterboxers in that vicinity are very active and have planted many interesting boxes. In fact, when you attend the St Louis event, you will meet several of them who have signed up to come.
