Welcome Laura

congrats for having the self confidence to get up and keep going!

I have visited Tijuana - Drivers there can be a little crazy so you all are doing well to take a stand. Be careful and wear bright clothing

Railroad tracks still make me nervous and the ones that aren't well maintained are the worst. I would definately get off and walk across them. Luckily you weren't injured but it only takes 1 good fall to lay you up for awhile

PS your English is way better than a lot of native speakers I know
