We would be grateful please for readers advice on whether it would be wise to spend a full 2 weeks in San Antonio. We love hiking and the great outdoors but my wife suffers from bites by flying insects. Is this a problem in SA? We also love mining for semi-precious gens, we spent a week last year in Arkansas mining for Crystals which was out of this world! Any advice offered would be greatly appreciated. UK to USA is a long way to go to make a mistake!
