If you are in CA and coming to the SD walk, feel free to send me an email that you are attending the walk and I will be sure to note t-shirt sizes for you. Our t-shirt deadline has been extended to April 11th, which is good news!
You can send in a registration brochure to the address listed or wait for the site to be up, which should be soon (or so I hear)! Be sure to send in a registration brochure for each walker, including children who are not receiving a t-shirt (for liability reasons), although one check can be written for the registration fees for your entire group.
Email me if you have questions.
