[Boris The Spider]

After giving it a quick once over I found little to be dissapointed with.
Here is what I noticed...

Missing River? Grid AO-6. Two bridges, one road, one rail, no visible reason. A dry gulch perhaps?.

Although there is a railroad on the South of the island, wouldn't there be one on the North as well? More and bigger towns would make use of a rail system I would think.
(Qualifier: I don't make maps. Perhaps laying rail is more difficult than roads.)

No Rum Factory!!! You would think in San Juan at least.....

I thought that the San Juan airfield, in the '50s, would have a civil terminal so.....


As well as an updated Control Tower:


and EMS station:


Now if I could just find that rum factory....
