Welcome to DW!
I lived for some time in rural Nevada, and after that, in rural Idaho. Here's what worked for me; it might work for you, too:
*Make a connection with a temple & teacher someplace where you can commute every month or six weeks to check in, attend big events, that sort of thing.
*Practice as best you can at home. When you have questions, call or email your teacher if possible. If not possible, load up your spacecraft and head to town...
*Repeat at regular intervals.
Your study & firm resolve to practice will carry you through.
Thanks to the help of generous sponsors (most of them from DharmaWheel), I'm doing a Vajra Armor (Dorje Kotrab) self-retreat this summer. May the merit be yours!
