so today I was diving jb. iw as extremely crowded and even had about 8-10 cave divers in there. On my second dive i went in about 20' and relized that I had not put anything on my mask and went back to get some de fog. On my way out i saw a guy with a single 80 and a pony bottle entering the cavern. i motioned him to go top side. once on the surface i asked my girlfriend to get me some defog from the car and asked the ow diver if he was cave trained. He said he was not and that him and his son were working on there advanced ow. i told him he should probaly stay out of the cave and he said they would. I got my mask strait and went back down. As I entered the cave sure enough they were well into the cavern. I stayed behind them for a bit and watched as the almost got themselves tangled in the line numerious times. there were to primary lines tied into the gold line. they swam ontop of them and numerious times got themselves tangled. I followed them all the way back the sign. as they stopped to read it i swam in front of them and pointed to the sign vigeriously and motioned them to leave the cave. they nodded and sat there for a minute. I decided i was going to swim further into the cave as i entered the cave i looked back and saw lights follow me. i turned my light off and waited to see if they kept comming in. they got almost tot he first break down before again i turned on my light and sat infri=ont of them and nearly phyc=sically pushed them out of the cave. i waited till they got all the way till the cavern and consinued my dive. there were numerious ow divers there today. these ones were in bc's single 80's and pistol grip lights. when will people learn? i thought jb was closed to all but cave trained divers??
