Fear not: simply create a Textmark so you can get arrival times via SMS. Check our handy guide to existing marks after the jump, and you'll never be caught waiting and waiting and waiting and waiting and waiting and waiting and waiting and waiting and waiting and waiting and waiting and waiting and waiting ever again. Post new marks in the comments as you create them!
