Tijuana
One of the few places we can fly directly to from Zihua is Tijuana. A couple of years ago we flew there and visited the Guadalupe Valley and checked out the local wine region. I can recommend that experience as it opened our eyes to the excellent wines produced there. Pity they are not exported to the extent that we can enjoy them at home (in Canada, my case). Something about production volumes and Mexican taxes making them expensive.
This year we are flying to Tijuana but are using CBX bridge to access the us into San Diego and we have paid for the tickets. Maybe someone knows if a Canadian has to fill in the I-94 form as some of the instructions are ambiguous. on their website.
