While sitting in the van, waiting to cross from Mexico into the US, I was bored. So, I engaged in some trivial pursuit. I did a rough estimate and came up with the possible number of round trips I have made from Mexico into Texas and from Texas back into Mexico. In almost 14 years, that comes to about 3,550 trÃps. And each round trip costs about $5.00 in tolls, depending on the current value of the dollar. So, that would mean that I have spent around $17,700 in tolls. And If I spent an average of 30 minutes of wait time on the bridge for each trip, that would mean about 106,080 minutes or 1,708 hours WAITING to cross the bridge. Now, I am sure that all my readers will find this information USEFUL!!!
