For 20 years members of the Tucson Garden Railway Society, a 501(c)(3) organization located here in southern Arizona, have opened their yards for visitors to enjoy the elaborate g-gauge train layouts which they have designed and constructed. This year’s self-guided tour will run over the second weekend in March, the 8th and 9th, from 10 am to 4 pm. The tour is free, but cash donations are collected for the community food bank. To date, over $20,000 has been donated to the Community Food Bank of Southern Arizona. A link to this year’s locations, as well as descriptions and directions, can be found at the TGRS website: http://tucsongrs.org/
